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 optimised 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 signalling) 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.
The AD7960 can be used with the ADA4897 low-power, rail-to-rail output amplifier, the AD8031 rail-to-rail I/O amplifier and the ADR4540 or the ADR4550 voltage references to provide a complete low-power, high-precision signal chain.
