Industry’s Fastest 18-Bit SAR A/D Converter Unveiled

  Industry’s Fastest 18-Bit SAR A/D Converter Unveiled

Business Wire

NORWOOD, Mass. -- September 4, 2013

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) converter. 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.

Related evaluation tools such as reference circuits, development kits and FPGA
mezzanine cards include all HDL code and device drivers for easy integration
with FPGAs and support faster development in a simplified design environment.
