19-2164; Rev 6; 1/06 High-Output-Drive, 10MHz, 10V/µs, Rail-to-Rail I/O Op Amps with Shutdown in SC70 The MAX4230 MAX4230­MAX4234 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 MAX4230­MAX4234 MAX4234 can drive typical headset levels (32), as well as bias an RF power amplifier (PA) in wireless handset applications. The MAX4230 MAX4230 comes in a tiny 5-pin SC70 package and the MAX4231 MAX4231, single with shutdown, is offered in the 6-pin SC70 package. The dual op-amp MAX4233 MAX4233 is offered in the space-saving 10-bump chip-scale package (UCSPTM), 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 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 MAX4230 family offers low offsets, wide bandwidth, and high-output drive in a tiny 2.1mm x 2.0mm spacesaving SC70 package. These parts are offered over the automotive temperature range (-40°C to +125°C).
