MAX4230–MAX4234 High-Output-Drive, 10MHz, 10V/μs, Rail-to-Rail I/O Op Amps with Shutdown in SC70 General Description Benefits and Features
The MAX4230–MAX4234 single/dual/quad, high-output ● Optimized for Headsets and High-Current Outputs drive CMOS op amps feature 200mA of peak output cur- • 200mA Output Drive Capability rent, rail-to-rail input, and output capability from a single • 100dB Voltage Gain (RL = 100kΩ) 2.7V to 5.5V supply. These amplifiers exhibit a high slew • 85dB Power-Supply Rejection Ratio rate of 10V/μs and a gain-bandwidth product (GBWP) of • No Phase Reversal for Overdriven Inputs 10MHz. The MAX4230–MAX4234 can drive typical headset • Unity-Gain Stable for Capacitive Loads to 780pF levels (32Ω), as well as bias an RF power amplifier (PA) ● Suitable for High-Bandwidth Applications in wireless handset applications. • 10MHz Gain-Bandwidth Product The MAX4230 comes in a tiny 5-pin SC70 package • High Slew Rate: 10V/μs and the MAX4231, single with shutdown, is offered in ● Extends the Battery Life of Portable Applications a 6-pin SC70 package and in 1.5mm x 1.0mm UCSP • 1.1mA Supply Current per Amplifier and thin μDFN 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 < 1μA (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. This ensures that the RF PA is fully disabled when needed,
