uP1816P中文资料3-Channel Current DAC数据手册uPI(UBIQ)规格书

描述 Description

The uP1816P is a high precision current console consistingof three sets I2C programmable current DACs. Each currentDAC is capable of sinking 128-step and sourcing 128-stepoutput currents that are programmed by the I2C interface.The sinking and sourcing currents of OUT1, OUT2, andOUT3 are programmable for 2x boost respectively.

The uP1816P features soft-jump, easily interfacing withstandard DC/DC converter for current console. The uP1816Pis available in space-saving SOT23 - 8L and WDFN2x2 - 8Lpackages.
