Overview
The AD5755ACPZ from Analog Devices Inc. is a quad, 16-bit digital-to-analog converter (DAC) that offers both voltage and current output capabilities. This device is designed to operate with a wide power supply range from −26.4 V to +33 V, making it versatile for various industrial applications. The AD5755ACPZ features on-chip dynamic power control, which minimizes package power dissipation in current mode by regulating the voltage on the output driver using a dc-to-dc boost converter. It also includes user-programmable offset and gain, on-chip diagnostics, and an on-chip reference with a maximum drift of ±10 ppm/°C. The device supports a temperature range of −40°C to +105°C.
