Analog Devices AD677

The AD677 is a multipurpose 16-bit serial output analog-todigital converter which utilizes a switched-capacitor/charge redistribution architecture to achieve a 100 kSPS conversion rate (10 µs total conversion time). The AD677 circuitry is segmented onto two monolithic chips— a digital control chip fabricated on Analog Devices DSP CMOS process and an analog ADC chip fabricated on our BiMOS II process. Both chips are contained in a single package.

DESCRIPTION

PRODUCT HIGHLIGHTS Overall performance is optimized by digitally correcting internal nonlinearities through on-chip autocalibration. Both chips are contained in a single package. The AD677 is specified for ac (or “dynamic”) parameters such as S/(N+D) Ratio, THD and IMD which are important in signal processing applications. In addition, dc parameters are specified which are important in measurement applications. The AD677 operates from +5 V and ± 12 V supplies and typically consumes 450 mW using a 10 V reference (360 mW with 5 V reference) during conversion.
