MAX4230MAX4234 High-Output-Drive, 10MHz, 10V/s, Rail-to-Rail I/O Op Amps with Shutdown in SC70 General Description Benefits and Features Optimized for Headsets and High-Current Outputs The MAX4230MAX4234 single/dual/quad, high-output 200mA Output Drive Capability drive CMOS op amps feature 200mA of peak output cur- 100dB Voltage Gain (R = 100k) rent, rail-to-rail input, and output capability from a single L 85dB Power-Supply Rejection Ratio 2.7V to 5.5V supply. These amplifiers exhibit a high slew No Phase Reversal for Overdriven Inputs rate of 10V/s and a gain-bandwidth product (GBWP) of Unity-Gain Stable for Capacitive Loads to 780pF 10MHz. The MAX4230MAX4234 can drive typical headset levels (32), as well as bias an RF power amplifier (PA) Suitable for High-Bandwidth Applications in wireless handset applications. 10MHz Gain-Bandwidth Product High Slew Rate: 10V/s The MAX4230 comes in a tiny 5-pin SC70 package Extends the Battery Life of Portable Applications and the MAX4231, single with shutdown, is offered in a 6-pin SC70 package and in 1.5mm x 1.0mm UCSP 1.1mA Supply Current per Amplifier and thin DFN packages. The dual op-amp MAX4233 is Low-Power Shutdown Mode Reduces Supply Current offered in the space-saving 10-bump chip-scale package to < 1A (UCSP), providing the smallest footprint area for a dual Small Package Options op amp with shutdown. Tiny, 2.1mm x 2.0mm Space-Saving SC70 Package These op amps are designed to be part of the PA control AEC-Q100 Qualified, See the Ordering Information circuitry, biasing RF PAs in wireless headsets. The MAX4231/ for the List of /V Parts MAX4233 offer a SHDN feature that drives the output low. Ordering Information This ensures that the RF PA is fully disabled when needed, preventing unconverted signals to the RF antenna.
