MAXIM MAX4230–MAX4234 数据手册

更新: 30 September, 2023

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 the 6-pin SC70 package and a 1.5mm x 1.0mm x 0.5mm ultra-thin µDFN 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).
