Overview
The AD5532BBCZ-1 is a 32-channel, 14-bit, bipolar, voltage-output Digital-to-Analog Converter (DAC) produced by Analog Devices Inc. This device integrates 32 DACs and an Analog-to-Digital Converter (ADC) for Infinite Sample-and-Hold (ISHA) mode within a single package. It is designed to provide high precision and reliability, making it suitable for a variety of applications requiring multiple analog output channels.
The AD5532BBCZ-1 operates with multiple power supply voltages: AVCC = +5 V ± 5%, DVCC = +2.7 V to +5.25 V, VSS = –4.75 V to –16.5 V, and VDD = +8 V to +16.5 V. It also requires a stable 3 V reference on REF_IN and an offset voltage on OFFS_IN. The device is available in a 74-lead CSPBGA package with a body size of 12 mm x 12 mm.
