Analog Devices, Inc.
(NASDAQ: ADI) introduced today an 18-bit PulSAR® A/D converter with 5-MSPS throughput that is twice the speed of any available SAR (successive-approximation register)
. With its industry leading throughput, best-in-class noise floor and high linearity, the AD7960 PulSAR A/D converter was designed for low-power signal chains, multiplexed systems such as digital X-ray, and oversampling applications including spectroscopy, MRI gradient control and gas chromatography.
Unlike other 18-bit A/D converters, which sacrifice power and accuracy to achieve higher sample rates, the AD7960 consumes 39 mW at 5 MSPS and is optimized for excellent DC linearity (+/- 0.8 LSB INL) and AC performance (99dB SNR) even at full throughput. The new converter also features a best-in-class noise floor (22.4 nV/√Hz) relative to its full scale input, which combined with a small package size helps designers meet space, thermal, power and other key design challenges common to high-channel-density systems.
Also today, Analog Devices introduced the AD7961 16-bit PulSAR A/D converter, which achieves excellent SNR (signal-to-noise ratio) performance (95.5 dB) and INL (+/- 0.2 LSB INL) at 5-MSPS.
AD7960 and AD7691 PulSAR A/D Converters Target Data Acquisition Systems
The AD7961 and AD7960 PulSAR A/D converters provide a pin-compatible upgrade/downgrade path for 16- and 18 –bit data acquisition applications in instrumentation and healthcare. They include a flexible, low-noise LVDS (low-voltage differential signaling) interface which transfers data off chip at speeds up to 300 MHz.
