March 11, 2014 – Analog Devices ( www.analog.com , NASDAQ: ADI), a global leader in high-performance semiconductors for signal processing applications, has released two new 18-bit A/D converters that combine the industry's lowest power consumption with excellent accuracy.

The power consumption of the AD7989-1 and AD7989-5 PulSAR® A/D converters is only 400µW at 100kSPS. Since power consumption increases with processing speed, addressing heat dissipation is critical in the design of densely packed data acquisition systems. The newly announced A/D converters feature ±1LSB at 1kHz and an SNR of 98dB for a high dynamic range, along with excellent accuracy and precision. Both products are available with 100kSPS and 500kSPS throughput options and include low-power, high-precision 18-bit sampling A/D converters and various serial interface ports.

The AD7989-1 and AD7989-5 PulSAR® A/D converters are the latest additions to Analog Devices' PulSAR product family. The PulSAR family includes 18-bit and 16-bit precision A/D converters supporting sampling rates ranging from 100 kSPS to 1 MSPS. These products are available in various pin-compatible versions to enable easy performance upgrades or downgrades in a wide range of markets, including battery-powered equipment, data acquisition systems, and medical measuring instruments.

The new A/D converter products can be used in data acquisition circuits with ADI's high-precision amplifiers and references, such as the ADA4841-2 and ADR434, which have low power, low noise, and low distortion characteristics.
