Three-Channel Current Console with SMBus Programmable Current DAC

Datasheets PDF

General Description

The uP1816Q is a high precision current console consisting of three sets SMBus programmable current DACs. Each current DAC is capable of sinking 128-step and sourcing 128-step output currents that are programmed by the SMBus interface. The sinking and sourcing currents of OUT1, OUT2, and OUT3 are programmable for 2x boost respectively.

The uP1816Q features soft-jump, easily interfacing with standard DC/DC converter for current console. The uP1816Q is available in the space-saving WDFN2x2 – 8L package.
