AD7991YRJZ-1RL Description

Short technical summary and product information.

The AD7991YRJZ-1RL is a 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Analog Devices. It offers a fast conversion time of 1 µs typical and a sampling rate of 140k samples per second. The device features a 4-channel multiplexer (3 channels with external reference) and provides a single-ended input configuration. It communicates via an I2C-compatible serial interface supporting standard, fast, and high speed modes.

 

Operating from a supply voltage of 2.7V to 5.5V, the AD7991YRJZ-1RL is designed for low-power applications. The typical conversion time is 1 µs, and the shutdown mode draws only 1 µA maximum. The ADC architecture is SAR (successive approximation register) with a track-and-hold amplifier capable of handling input frequencies up to 14 MHz.

 

The device is housed in an 8-lead SOT-23 surface-mount package, suitable for space-constrained designs. It is specified over the extended industrial temperature range of -40°C to +125°C, making it suitable for harsh environments. Typical applications include battery-powered systems, data acquisition, and medical instruments.

 

The AD7991YRJZ-1RL is RoHS compliant and has a moisture sensitivity level of 1 (unlimited), though these certifications are unverified. It is important to verify compliance status with the manufacturer for specific requirements.
