Description

The MAX881R IC is an inverting, charge-pump DC-DC converter with a low-noise, regulated output. Low output ripple voltage makes this device ideal for biasing the GaAsFETs commonly found in cellular telephone transmitters.

The MAX881R evaluation kit (EV kit) is a fully assembled and tested surface-mount board. Provisions are made for mounting a second voltage-divider resistor, which is required for setting output voltages other than -2V. A special scope-probe socket is also mounted on the board, so output noise can be observed on an oscilloscope.
