19-4105; Rev 1; 1/09 KIT ATION EVALU E L B AVAILA Ultra-Small, Low-Power Single Comparators in 4-Bump UCSP and 5-SOT23 The MAX9060-MAX9064 are small single comparators, ideal for a wide variety of portable electronics applications such as cell phones, media players, and notebooks that have extremely tight board space and power constraints. These comparators are offered in both, a miniature 4-bump UCSPTM package with a 1mm x 1mm footprint (as small as two 0402 resistors), and a 5-pin SOT23 package. The MAX9060-MAX9064 feature an input voltage range of -0.3V to +5.5V independent of supply voltage. These devices maintain high impedance at the inputs even when powered down (VCC or VREF = 0V). They also feature internal filtering to provide high RF immunity. The MAX9060 and MAX9061 have open-drain outputs and draw quiescent supply current from a user-supplied reference voltage, VREF, between 0.9V and 5.5V. These devices consume only 100nA (max) supply current and operate over the extended -40C to +85C temperature range. The MAX9062, MAX9063 and MAX9064 are single comparators with an internal 0.2V reference. These devices feature either a push-pull or an open-drain output. They consume only 700nA (max) supply current. The MAX9062, MAX9063, and MAX9064 operate down to VCC = 1V over the extended -40C to +85C temperature range.

Detailed Description The MAX9060-MAX9064 are extremely small comparators ideal for compact, low-current, and lowvoltage applications. The MAX9060/MAX9061 consume only 50nA (typ) operating current, while the MAX9062/MAX9063/MAX9064 consume only 400nA (typ). The low-voltage operating capability of the MAX9060-MAX9064 makes these devices extremely attractive to long-life battery-operated devices--these applications can now use a single digital power-supply rail to power the new generation of microcontrollers (which can be down to 0.9V). A single AA/AAA cell can drop down to 0.9V in full discharge. All parts are available in a tiny 4-bump UCSP, that is only 0.6mm tall, and occupies a 1mm x 1mm footprint and a 5-pin SOT23. Input Stage Circuitry Noninverting inputs are available on the MAX9060/ MAX9062/MAX9064 and inverting inputs are available on the MAX9061/MAX9063. The MAX9060-MAX9064 incorporate an innovative input stage architecture that allows their input voltage to exceed VCC by several volts (limited only by the Absolute Maximum Ratings). This is unlike traditional FUNCTION comparators that have an input ESD diode clamp between the input and VCC, limiting this maximum overvoltage to about 0.3V. The MAX9060-MAX9064 architecture maintains a high input impedance to input signals even when the device power-supply voltage is completely turned off (VCC or REF taken to 0V). This greatly benefits flexible power-saving schemes to be easily implemented in advanced battery-operated devices. On-chip filtering provides immunity from any RF noise being picked up by input traces. These devices feature an internal temperature-compensated, low-power 0.2V reference voltage. Output Stage Structure The MAX9060-MAX9063 have open-drain outputs that allow them to interface to logic circuitry running from supply voltages other than the one supplied to the part. These devices require an external pullup resistor or current source for proper operation. Many microcontroller digital inputs ports can be readily programmed to include these. The MAX9064 has a push-pull output stage that can both sink and source current, eliminating the need for an external pullup resistor. In this case, the MAX9064 uses the microcontroller's power supply as VCC. _______________________________________________________________________________________ 7 MAX9060-MAX9064 Pin Description MAX9060-MAX9064 Ultra-Small, Low-Power Single Comparators in 4-Bump UCSP and 5-SOT23 Table 1.

Applications Information Bypassing REF/VCC Place a 0.1F capacitor between REF or V CC and GND as close as possible to the device. During a switching event, all comparators draw a current spike from their power-supply rails. This current spike is minimized by the use of an internal break-before-make design. Hysteresis Operation The MAX9060-MAX9064 feature internal hysteresis for noise immunity and glitch-free operation. If additional hysteresis is needed, an external positive feedback network can be easily implemented on the MAX9060, MAX9062, and MAX9064 noninverting input devices. Additional external hysteresis is not recommended for the MAX9061 due to possible crossover current-related noise problems. Additional external hysteresis is not possible on the MAX9063 because the noninverting input of the comparator is not externally accessible. Adaptive Signal Level Detector The MAX9060 and MAX9061 can be used as an adaptive signal-level detector. Feed a DAC output voltage to REF and connect the input to a variable signal level. As the DAC output voltage is varied from 0.9V to 5.5V, a corresponding signal level threshold-detector circuit is implemented. See Figure 1.
