Released Today: Industry’s Lowest Power 18-bit SAR A/D Converters

AD7989-1 and AD7989-5 PulSAR ® A/D converters provide low power, high precision solutions for portable applications.

Mar 6 2014 - Norwood, MA
  • Analog Devices, Inc. (NASDAQ: ADI) introduced today two 18-bit A/D converters that combine the industry’s lowest power with excellent accuracy. The AD7989-1 and AD7989-5 PulSAR® A/D converters consume 400 µW at 100 kSPS. Power consumption is scaled depending on throughput speed to address thermal dissipation challenges in dense data acquisition system designs. The A/D converters feature +/-1 LSB and 98 dB SNR at 1 kHz for high dynamic range with exceptional accuracy and precision. Both A/D converters are available in 100 kSPS and 500 kSPS throughput options, incorporate a low power, high precision, 18-bit sampling A/D converter and a versatile serial interface port.

    The AD7989-1 and AD7989-5 PulSAR® A/D converters are the newest additions to Analog Devices’ PulSAR portfolio. The PulSAR portfolio includes 18- and 16-bit A/D precision converters ranging from 100 kSPS to 1 MSPS. They provide a versatile pin-compatible upgrade/downgrade path for performance in a wide range of markets including battery-powered equipment, data acquisition systems and medical instrumentation.
