Analog Devices Intros AD7686 SAR Converter

June 01, 2003 by Jeff Shepard

Analog Devices Inc. (Wilmington, MA) presented its new successive-approximation register (SAR) converter, the AD7686, which joins Analog Devices' extensive PulSAR™ family. The new 16-bit, SAR analog-to-digital (ADC) converter is available in a 5mm x 3mm, micro-SOIC package (MSOP), compact package, which operates at 550kSPS (kilo samples per second) while providing ±3LSB linearity. It offers a typical power dissipation of 20mW with a 2.7V supply. Applications include portable medical and battery-operated equipment, manufacturing process control systems, and data acquisition systems.

The AD7686 offers designers 16 bits of no missing codes, INL of ±3LSB (maximum), SNR of 89dB (typical at 10kHz), no pipeline delays, and a pin-for-pin upgrade path with the company's 16-bit PulSAR product family. The device features fully differential inputs, a conversion clock and a serial interface.

The AD7686 is sampling now and will be in full production in December 2003. Follow-on products will have differential analog inputs and ±1.5LSB INL performance. The AD7686 is housed in a 10-lead MSOP with operation specified from -40°C to +85°C. The device is priced at $12 per unit in 1,000-piece quantities.
