Tiny, 2.1mm x 2.0mm Space-Saving SC70 Package

The MAX4230–MAX4234 single/dual/quad, high-output

drive CMOS op amps feature 200mA of peak output cur-

rent, 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these

or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect

device reliability.
