The AD7891ASZ-2 is a high-speed, 12-bit data acquisition system (DAS) from Analog Devices. It integrates an 8-channel input multiplexer, track/hold amplifier, 12-bit ADC, 2.5V reference, and high-speed interface in a single 44-MQFP package. The device offers a conversion time of 1.6 µs and an acquisition time of 0.4 µs, enabling a sampling rate of 500 kSPS. It supports both serial and parallel data interfaces for flexible system integration.
The AD7891-2 variant accepts analog input ranges of 0 to +2.5V, 0 to +5V, and ±2.5V. It operates from a single 5V supply with typical power dissipation of 82 mW in normal mode and 75 µW in standby mode. The device is specified for the industrial temperature range of -40°C to +85°C.
Typical applications include data acquisition systems, motor control, mobile communication base stations, and instrumentation. The surface-mount 44-MQFP (10x10 mm) package is suitable for space-constrained designs. The part is RoHS3 compliant (unverified) and has an MSL of 1 (unlimited).
