AD7891AP-1 Description

Short technical summary and product information.

The AD7891AP-1 is an 8-channel, 12-bit data acquisition system (DAS) from Analog Devices, designed for high-speed data acquisition applications. It integrates an input multiplexer, track/hold amplifier, 12-bit SAR ADC, 2.5V reference, and high-speed parallel/serial interface in a single 44-PLCC package. The device operates from a single 5V supply and accepts analog input ranges of ±5V and ±10V for the AD7891-1 model.

 

Key performance specifications include a 500kS/s sampling rate, 1.6µs typical conversion time, 0.4µs acquisition time, and 82mW typical power dissipation (100mW max). The standby power consumption is only 75µW. The ADC architecture is successive approximation register (SAR), providing fast and accurate conversions.

 

This DAS is suitable for data acquisition systems, motor control, mobile communication base stations, and instrumentation. The surface mount 44-PLCC package with J-leads supports compact PCB layouts. The device is specified for the industrial temperature range of -40°C to 85°C.
