Description
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.
