AD7821KRZ Description

Short technical summary and product information.

The AD7821KRZ is an 8-bit, high-speed, sampling analog-to-digital converter (ADC) from Analog Devices. It utilizes a pipelined architecture to achieve a maximum conversion time of 660 ns and a sampling rate of 1 MSPS. The device includes an integrated track-and-hold function capable of digitizing full-scale signals up to 100 kHz, making it suitable for applications requiring high throughput.

 

Key electrical specifications include a single-ended input, external voltage reference, and parallel data interface. The ADC operates from a single 5V supply (or ±5V with VSS pin) and dissipates typically 50 mW. It offers a total unadjusted error of ±1 LSB maximum over the full temperature range of -40°C to +85°C.

 

The AD7821KRZ is housed in a 20-pin SOIC package (0.295" width, 7.50mm) with surface mount mounting. It is designed for easy interfacing with microprocessors using standard control signals (CS, RD, WR, RDY, INT) and three-state data outputs. The device is RoHS3 compliant (unverified) and has an MSL rating of 1 (unlimited).
