Analog Devices introduces "fastest, most accurate" 16bit SAR converter

Analog Devices has introduced what it claims as the "fastest, most accurate 16bit successive-approximation register (SAR) analog-to-digital converter (ADC) available in a compact package."
The new SAR converter–AD7686–joins Analog Devices' PulSAR(TM) family of SAR converters which are based on an ADC architecture that provides the added advantage of zero data latency which is critical in data acquisition systems.
Its high performance features in a small package makes it suited for a variety of high-precision portable applications, such as portable medical and battery-operated equipment. The device offers designers 16bits of no missing codes, INL of 63 LSB(max.), SNR of 89dB (typical at 10kHz), no pipeline delays, and a pin-for-pin upgrade path with Analog Devices' 16bit PulSAR product family. The 16bit, 550kSPS device features uni-polar inputs, a conversion clock, and a serial interface.
Housed in a 5 3 3mm MSOP (micro-SOIC package), the new ADC operates at 550kSPS (kilo samples per second) while providing 63 LSB linearity. It is also claimed to be the lowest power 16bit SAR ADC at this sampling rate with typical power dissipation of 20mW with a 2.7V supply.
The AD7686 is sampling now and will be in full production in December 2003. Follow-on products will have differential analog inputs and 61.5LSB INL performance. Housed in a 10-lead MSOP with operation specified from -40 to +858C, the converter is priced at US$12 (1000).
