Product Overview
AD5755-1ACPZ from ADI is a quad 16-bit DAC with software-selectable current or voltage output. HART multiplexer. 4-20mA and 0-10V ranges. LFCSP-40.
Working Principle
Four independent 16-bit DAC channels. Each can be configured for voltage (0-5V, 0-10V, +/-10V) or current (4-20mA, 0-20mA, 0-24mA). Internal HART signal coupling. SPI interface. Internal fault detection.
