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 single 2.7V to 5.5V supply. These amplifiers exhibit 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 a 6-pin SC70 package and in 1.5mm x 1.0mm UCSP™ and thin µDFN packages. The dual op-amp MAX4233 offered in the space-saving 10-bump chip-scale package (UCSP), providing the smallest footprint area for a dual op amp with shutdown.

These op amps are designed to be part of the PA control circuitry, biasing RF PAs in wireless headsets. The MAX4231/MAX4233 offer a active-low SHDN feature that drives the output low. This ensures that the RF PA is fully disabled when needed, preventing unconverted signals to the RF antenna.

Applications

  • Audio Hands-Free Car Phones (Kits)
  • Digital-to-Analog Converter Buffers
  • Motor Drivers
  • Portable Headphone Speaker Drivers (32Ω)
  • Portable/Battery-Powered Audio Applications
  • RF PA Biasing Controls in Handset Applications
  • Tablet/Notebook Computers
  • Transformer/Line Drivers
