Detailed Description
Rail-to-Rail Input Stage
The MAX4490/MAX4491/MAX4492 CMOS operational
amplifiers have parallel-connected N- and P-channel
differential input stages that combine to accept a com-
mon-mode range extending to both supply rails. The N-
channel stage is active for common-mode input
voltages typically greater than (VSS + 1.2V), and the P-
channel stage is active for common-mode input volt-
ages typically less than (VDD - 1.2V).
Rail-to-Rail Output Stage
The MAX4490/MAX4491/MAX4492 CMOS operational
amplifiers feature class-AB push-pull output stages that
can drive a 100k
load to within 1.5mV of either supply
rail. Short-circuit output current is typically ±50mA.
Figures 1a and 1b show the typical temperature depen-
dence of output source and sink currents, respectively,
for three fixed values of (VDD - VOH) and (VOL - VSS).
For example, at VDD = 5.0V, the load currents that main-
tain (VDD - VOH) = 100mV and (VOL - VSS) = 100mV at
TA = +25°C are 2.2mA and 3.3mA, respectively, when
the load is connected to VDD/2. Consistent resistive-
drive capability is (2.5 - 0.1) / 2.2 = 1.1k
. For the same
application, resistive-drive capability is 2.2k
when the
load is connected to VDD or VSS.
Applications Information
Power-Supply Considerations
The MAX4490/MAX4491/MAX4492 operate from a sin-
gle 2.7V to 5.5V supply or from dual ±1.35V to ±2.75V
supplies with typically 800A supply current per ampli-
fier. A high power-supply rejection ratio of 100dB
allows for extended operation from a decaying battery
voltage, thereby simplifying designs for portable appli-
cations. For single-supply operation, bypass the power
supply with a 0.1F ceramic capacitor placed close to
the VDD pin. For dual-supply operation, bypass each
supply to ground.
Input Capacitance
One consequence of the parallel-connected differential
input stages for rail-to-rail operation is a relatively large
input capacitance CIN (typically 5pF). This introduces a
