MAX4230–MAX4234 High-Output-Drive, 10MHz, 10V/μs,
Rail-to-Rail I/O Op Amps with Shutdown in SC70 General Description The MAX4230–MAX4234 single/dual/quad, high-output
drive CMOS op amps feature 200mA of peak output current, rail-to-rail input, and output capability from a single
2.7V to 5.5V supply. These amplifiers exhibit a high slew
rate of 10V/μs and a gain-bandwidth product (GBWP) of
10MHz. The MAX4230–MAX4234 can drive typical headset
levels (32Ω), as well as bias an RF power amplifier (PA)
in wireless handset applications.
The MAX4230 comes in a tiny 5-pin SC70 package
and the MAX4231, single with shutdown, is offered in
a 6-pin SC70 package and in 1.5mm x 1.0mm UCSP
and thin μDFN packages. The dual op-amp MAX4233 is
offered in the space-saving 10-bump chip-scale package
(UCSP™), providing the smallest footprint area for a dual
op amp with shutdown.
These op amps are designed to be part of the PA control
circuitry, biasing RF PAs in wireless headsets. The MAX4231/
MAX4233 offer a SHDN feature that drives the output low.
This ensures that the RF PA is fully disabled when needed,
preventing unconverted signals to the RF antenna. Applications
