General Description
The The MAX4230–MAX4234 single/dual/quad, high-
outputdrive 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 cir-
cuitry, 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.
The MAX4230 family offers low offsets, wide bandwidth,
and high-output drive in a tiny 2.1mm x 2.0mm spacesav-
ing SC70 package. These parts are offered over the auto-
motive temperature range (-40°C to +125°C).
