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 (32 ), 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 the
6-pin SC70 package. 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).
