Detailed Description

Rail-to-Rail Input Stage

The MAX4230âMAX4234 CMOS operational amplifiers

have parallel-connected n- and p-channel differential

input stages that combine to accept a common-mode

range extending to both supply rails. The n-channel

stage is active for common-mode input voltages typi-

cally greater than (VSS + 1.2V), and the p-channel

stage is active for common-mode input voltages typi-

cally less than (VDD - 1.2V).

Applications Information

Package Power Dissipation

Warning: Due to the high output current drive, this op

amp can exceed the absolute maximum power-dissi-

pation rating. As a general rule, as long as the peak cur-

rent is less than or equal to 40mA, the maximum package

power dissipation is not exceeded for any of the package

types offered. There are some exceptions to this rule,

however. The absolute maximum power-dissipation rating

of each package should always be verified using the fol-

lowing equations. The equation below gives an approxi-

mation of the package power dissipation:

PIC(DISS) â VRMS IRMS COS Î¸

where:

VRMS = RMS voltage from VDD to VOUT when sourcing

current and RMS voltage from VOUT to VSS when sink-

ing current.

IRMS = RMS current flowing out of or into the op amp

and the load.

Î¸ = phase difference between the voltage and the cur-

rent. For resistive loads, COS Î¸ = 1.
