... The crossover region of these two pairs occurs halfway between V and V CC voltage is typically ±200µV (MAX4292/MAX4294). Low operating supply voltage, low supply current, rail-to-rail common-mode input range, and rail-to-rail outputs make this family of operational amplifiers (op amps) an excellent choice for precision or general-purpose, low- voltage, battery-powered systems ...

... A high power-supply rejection ratio of 100dB allows the amplifiers to be powered directly off a decaying battery voltage, simplifying design and extending battery life. The MAX4291/MAX4292/MAX4294 are ideally suited for use with most battery-powered systems. Table 1 lists a MAX4291 CAPACITY, AA SIZE OPERATING TIME IN ...

... Figures 6a and 6b show the typical current source and sink capabilities of the MAX4291/MAX4292/MAX4294 family as a function of supply voltage and ambient tem- perature. The contours on the graph depict the output current value, based on driving the output voltage to within 50mV, 100mV, and 200mV of either power-sup- ply rail ...

... Using the MAX4291/MAX4292/MAX4294 Although optimized for use as operational amplifiers, the MAX4291/MAX4292/MAX4294 can also be used as load resistor rail-to-rail I/O comparators. Typical propagation delay depends on the input overdrive voltage, as shown in Figure 8. External hysteresis can be used to minimize the risk of output oscillation. The positive feedback cir- cuit, shown in Figure 9, causes the input threshold to change when the output voltage changes state ...

... CC Using the MAX4291/MAX4292/MAX4294 as Low-Power Current Monitors The MAX4291/MAX4292/MAX4294 are ideal for appli- cations powered from a two-cell battery stack. Figure 11 shows an application circuit in which the MAX4291 is used for monitoring the current of a two-cell battery stack. In this circuit, a current load is applied, and the voltage drop at the battery terminal is sensed ...
