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 pack-
age (UCSP™), providing the smallest footprint area for
a dual op amp with shutdown.
These op amps are designed to be part of the PA con-
trol 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 dis-
abled 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 space-
saving SC70 package. These parts are offered over the
automotive temperature range (-40°C to +125°C).
