General Description

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.
