AD5770RBCBZ-RL7

Overview

The AD5770RBCBZ-RL7 is a 6-channel, 14-bit current output digital-to-analog converter (DAC) from Analog Devices. It features an integrated 1.25 V voltage reference and precision resistor. Channel 0 supports sourcing up to 300 mA and sinking up to 60 mA, while Channels 1 through 5 offer programmable sourcing ranges. The device utilizes an SPI interface for control and includes diagnostic monitoring for output current, compliance voltage, and die temperature. It operates within a supply range of 2.9 V to 5.5 V and is housed in a 49-ball WLCSP package.
