General Description

The MAX4230¨CMAX4234 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/?s and a gain-bandwidth product (GBWP) of 10MHz. The MAX4230¨CMAX4234 can drive typical headset levels (32¦¸), as well as bias an RF power amplifier (PA) in wireless handset applications.
