MAX9039-MAX9043/ MAX9050-MAX9053 Micropower, Single-Supply, UCSP/SOT23 Comparator + Precision Reference ICs General Description Features The MAX9039-MAX9043 and MAX9050-MAX9053 feature combinations of low-power comparators and precision voltage references. Their operating voltage range makes them ideal for both 3V and 5V systems. The MAX9039/MAX9040/MAX9041/MAX9050/MAX9051 have a single comparator and reference consuming only 40A of supply current. The MAX9042/MAX9043/ MAX9052/MAX9053 have dual comparators and one reference, and consume only 55A of supply current. Low-voltage operation and low supply current make these devices ideal for battery-operated systems. o Comparator + Precision Reference in UCSP/SOT23 The comparators feature rail-to-rail inputs and outputs, with a common-mode input voltage range that extends 250mV beyond the supply rails. Input bias current is typically 1.0pA, and input offset voltage is typically 0.5mV. Internal hysteresis ensures clean output switching, even with slow-moving input signals. The output stage features a unique design that limits supply current surges while switching, virtually eliminating supply glitches typical of many other comparators. This design also minimizes overall power consumption under dynamic conditions. The comparator outputs have railto-rail, push-pull output stages that sink and source up to 8mA. The propagation delay is 400ns, even with the low-operating supply current. o Internal 3mV Hysteresis The reference output voltage is set to 1.23V in the MAX9039, to 2.048V in the MAX9040-MAX9043, and to 2.500V in the MAX9050-MAX9053. The MAX9040- MAX9043 and the MAX9050-MAX9053 are offered in two grades: an A grade with 0.4% initial accuracy and 6ppm/C tempco, and a B grade with 1% initial accuracy (MAX9039 has an initial accuracy of 0.4%) and 100ppm/C tempco. The voltage references feature a proprietary curvature-correction circuit and lasertrimmed thin-film resistors. These series-mode references can sink or source up to 500A of load current.

This limit permits only the use of the solder profiles recommended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and Convection Packaging Reflow. Preheating is required. Hand or wave soldering is not allowed. Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

They operate from a single 2.5V to 5.5V (MAX9039/MAX904_) or 2.7V to 5.5V (MAX905_) supply. The single comparators with reference, (MAX9039/MAX9040/MAX9041/MAX9050/ MAX9051 consume only 40A of supply current, while the dual comparators with reference (MAX9042/ MAX9043/MAX9052/MAX9053) consume only 55A of supply current. Their common-mode input range extends 0.25V beyond each rail. Internal hysteresis ensures clean output switching, even with slow-moving input signals. The output stage employs a unique design that minimizes supply current surges while switching, virtually eliminating the supply glitches typical of many other comparators. Large internal output drivers allow rail-to-rail output swing that can sink and source up to 8mA of current. The precision reference uses a proprietary curvaturecorrection circuit and laser-trimmed thin-film resistors, resulting in a temperature coefficient of less than 30ppm/C over the extended temperature range and initial accuracy of 0.4% (A grade). The reference output voltage is set to 1.23V in the MAX9039, 2.048V in the MAX9040MAX9043, and to 2.500V in the MAX9050-MAX9053. Comparator Input Stage Circuitry The devices' input common-mode range extends from (VEE - 0.25V) to (VCC + 0.25V). These comparators may operate at any differential input voltage within these limits. Input bias current is typically 1.0pA if the input voltage is between the supply rails. Comparator inputs are R1 R2 VREF VCC IN- MAX9039-MAX9043 MAX9050-MAX9053 VEE Maxim Integrated Applications Information Additional Hysteresis These comparators have 3mV internal hysteresis. Additional hysteresis can be generated with two resistors using positive feedback (Figure 1). Use the following procedure to calculate resistor values: 1) Calculate the trip points of the comparator using these formulas: ( ) V CC - VREF R2 VTH = VREF + R1 + R2 and IN+ Figure 1. Additional Hysteresis Comparator Output Stage Circuitry The comparators in these devices contain a unique output stage capable of rail-to-rail operation with loads up to 8mA. Many comparators consume orders-of-magnitude more current during switching than during steady-state operation. However, with this family of comparators, the supply current change during an output transition is extremely small. The Typical Operating Characteristics graph Supply Current vs. Switching Frequency shows the minimal supply current increase as the output switching frequency approaches 1MHz. This characteristic reduces the need for power-supply filter capacitors to reduce glitches created by comparator switching currents. Another advantage realized in high-speed, battery-powered applications is a substantial increase in battery life. VCC OUT VIN protected from overvoltage by internal body diodes connected to the supply rails. As the input voltage exceeds the supply rails, these body diodes become forward biased and begin to conduct. Consequently, bias currents increase exponentially as the input voltage exceeds the supply rails. R2 VTL = VREF 1 - R1 + R2 VTH is the threshold voltage at which the comparator switches its output from high to low as V IN rises above the trip point. VTL is the threshold voltage at which the comparator switches its output from low to high as VIN drops below the trip point. 2) The hysteresis band will be: 3) In this example, let VCC = 5V and VREF = 2.5V: R2 VHYS = VTH - VTL = VCC R1 + R2 9 MAX9039-MAX9043/ MAX9050-MAX9053 Micropower, Single-Supply, UCSP/SOT23 Comparator + Precision Reference ICs VCC VCC IN+ VIN OUT 10k IN- 0.1F MAX9039-MAX9043 MAX9050-MAX9053 VEE Figure 2. Time Averaging of the Input Signal for Data Recovery R2 VTH = 2.5 + 2.5 R1 + R2 and R2 VTL = 2.5 1 - R1 + R2 4) Select R2. In this example, we will choose 1k. 5) Select VHYS. In this example, we will choose 50mV. 6) Solve for R1: R2 VHYS = VCC R1 + R2 1000 0.050 = 5 R1 +1000 where R1 100k, VTH = 2.525V, and VTL = 2.475V. Board Layout and Bypassing Power-supply bypass capacitors are not typically needed, but would be called for in cases where supply impedance is high, supply leads are long, or excessive noise is expected on the supply lines. Use 100nF bypass capacitors under these conditions. Minimize signal trace lengths to reduce stray capacitance. Reference Output/Load Capacitance applications where the load or the supply can experience step changes, an output capacitor will reduce the amount of overshoot (or undershoot) and assist the circuit's transient response. When an application is not subject to transient conditions, the REF capacitor can be omitted. Biasing for Data Recovery Digital data is often embedded into a bandwidth- and amplitude-limited analog path. Recovering the data can be difficult. Figure 2 compares the input signal to a time-averaged version of itself. This self-biases the threshold to the average input voltage for optimal noise margin. Even severe phase distortion is eliminated from the digital output signal. Be sure to choose R1 and C1 so that: fCAR >> 1 2R1C1 where fCAR is the fundamental carrier frequency of the digital data stream. UCSP Reliability The chip-scale package (UCSP) represents a unique packaging form factor that may not perform equally to a packaged product through traditional mechanical reliability tests. UCSP reliability is integrally linked to the user's assembly methods, circuit board material, and usage environment. The user should closely review these areas when considering use of a UCSP. Performance through Operating Life Test and Moisture Resistance remains uncompromised as it is primarily determined by the wafer-fabrication process. Mechanical stress performance is a greater consideration for a UCSP. UCSPs are attached through direct solder contact to the user's PCB, foregoing the inherent stress relief of a packaged product lead frame. Solder joint contact integrity must be considered. Information on Maxim's qualification plan, test data, and recommendations are detailed in the UCSP application note, which can be found on Maxim's website at www.maximintegrated.com.
