19-2016; Rev 1; 4/05 Ultra-Small, Rail-to-Rail I/O with Disable, Single-/Dual-Supply, Low-Power Op Amps The MAX4245/MAX4246/MAX4247 family of low-cost op amps offer rail-to-rail inputs and outputs, draw only 320A of quiescent current, and operate from a single +2.5V to +5.5V supply. For additional power conservation, the MAX4245/MAX4247 offer a low-power shutdown mode that reduces supply current to 50nA, and puts the amplifiers' outputs in a high-impedance state. These devices are unity-gain stable with a 1MHz gain-bandwidth product driving capacitive loads up to 470pF. The MAX4245/MAX4246/MAX4247 family is specified from -40C to +125C, making them suitable for use in a variety of harsh environments, such as automotive applications. The MAX4245 single amplifier is available in ultra-small 6-pin SC70 and space-saving 6-pin SOT23 packages. The MAX4246 dual amplifier is available in 8-pin SOT23, SO, and MAX(R) packages. The MAX4247 dual amplifier comes in a tiny 10-pin MAX package.

Minimizing Offset Error Due to Input Bias Current (Noninverting) Detailed Description Rail-to-Rail Input Stage The MAX4245/MAX4246/MAX4247 have rail-to-rail input and output stages that are specifically designed for low-voltage, single-supply operation. The input stage consists of composite NPN and PNP differential stages, which operate together to provide a common-mode range extending to both supply rails. The crossover region of these two pairs occurs halfway between VDD and VSS. The input offset voltage is typically 400V. Low-operating supply voltage, low supply current and rail-to-rail outputs make this family of operational amplifiers an excellent choice for precision or general-purpose, low-voltage, battery-powered systems. Since the input stage consists of NPN and PNP pairs, the input bias current changes polarity as the common- R1 R2 Figure 1b. Minimizing Offset Error Due to Input Bias Current (Inverting) mode voltage passes through the crossover region. Match the effective impedance seen by each input to reduce the offset error caused by input bias currents flowing through external source impedance (Figures 1a and 1b). The combination of high-source impedance plus input capacitance (amplifier input capacitance plus stray capacitance) creates a parasitic pole that can produce an underdamped signal response. Reducing input capacitance or placing a small capacitor across the feedback resistor improves response in this case. The MAX4245/MAX4246/MAX4247 family's inputs are protected from large differential input voltages by internal 5.3k series resistors and back-to-back triple-diode stacks across the inputs (Figure 2). For differentialinput voltages much less than 2.1V (triple-diode drop), _______________________________________________________________________________________ 7 MAX4245/MAX4246/MAX4247 Pin Description MAX4245/MAX4246/MAX4247 Ultra-Small, Rail-to-Rail I/O with Disable, Single-/Dual-Supply, Low-Power Op Amps 5.3k IN- IN 2V/div OUT 2V/div IN+ 5.3k Figure 2. Input Protection Circuit input resistance is typically 4M. For differential voltages greater than 2.1V, input resistance is around 10.6k, and the input bias current can be approximated by the following equation: 400s/div Figure 3. Rail-to-Rail Input/Output Voltage Range IB = (VDIFF - 2.1V) / 10.6k In the region where the differential input voltage approaches 2.1V, the input resistance decreases exponentially from 4M to 10.6k as the diodes begin to conduct. It follows that the bias current increases with the same curve. In unity-gain configuration, high slew-rate input signals may capacitively couple to the output through the triple-diode stacks. Rail-to-Rail Output Stage The MAX4245/MAX4246/MAX4247 can drive a 2k load and still typically swing within 35mV of the supply rails. Figure 3 shows the output voltage swing of the MAX4245 configured with AV = -1V/V. Applications Information Power-Supply Considerations The MAX4245/MAX4246/MAX4247 operate from a single +2.5V to +5.5V supply (or dual 1.25V to 2.75V supplies) and consume only 320A of supply current per amplifier. A 90dB power-supply rejection ratio allows the amplifiers to be powered directly off a decaying battery voltage, simplifying design and extending battery life. Power-Up The MAX4245/MAX4246/MAX4247 output typically settles within 4s after power-up. Figure 4 shows the output voltage on power-up and power-down. Shutdown Mode The MAX4245/MAX4247 feature a low-power shutdown mode. When SHDN_ is pulled low, the supply current drops to 50nA per amplifier, the amplifier is disabled, and the output enters a high-impedance state. Pulling 8 2V/div VDD 2V/div OUT 10s/div Figure 4. Power-Up/Power-Down Waveform SHDN_ high enables the amplifier. Figure 5 shows the MAX4245/MAX4247's shutdown waveform. Due to the output leakage currents of three-state devices and the small internal pullup current for SHDN_, do not let the SHDN_ float. Floating SHDN_ may result in indeterminate logic levels, and could adversely affect op amp operation. The logic threshold for SHDN_ is referred to VSS. When using dual supplies, pull SHDN_ to VSS, not GND, to shut down the op amp. Driving Capacitive Loads The MAX4245/MAX4246/MAX4247 are unity-gain stable for loads up to 470pF. Applications that require greater capacitive drive capability should use an isolation resistor between the output and the capacitive load _______________________________________________________________________________________ Ultra-Small, Rail-to-Rail I/O with Disable, Single-/Dual-Supply, Low-Power Op Amps MAX4245/MAX4246/MAX4247 2V/div RISO OUT SHDN IN RL CL 2V/div Figure 6a.

Note that this alternative results in a loss of gain accuracy because RISO forms a voltage divider with the RLOAD. 100mV/div IN Power-Supply Bypassing and Layout The MAX4245/MAX4246/MAX4247 family operates from either a single +2.5V to +5.5V supply or dual 1.25V to 2.75V supplies. For single-supply operation, bypass the power supply with a 100nF capacitor to VSS (in this case GND). For dual-supply operation, both the VDD and the VSS supplies should be bypassed to ground with separate 100nF capacitors. Good PC board layout techniques optimize performance by decreasing the amount of stray capacitance at the op amp's inputs and output. To decrease stray capacitance, minimize trace lengths and widths by placing external components as close to the device as possible. Use surface-mount components when possible. 100mV/div OUT 10s/div Figure 6b.
