PRODUCT DESCRIPTION

The AD1876 is a 16-bit serial output sampling A/D converter which uses a switched capacitor/charge redistribution architecture to achieve a 100 kSPS conversion rate (10 μs total conversion time). Overall performance is optimized by digitally correcting internal nonlinearities through on-chip autocalibration. The circuitry of the AD1876 is partitioned onto two monolithic chips, a digital control chip fabricated with Analog Devices’ DSP CMOS process and an analog ADC chip fabricated with the BiMOS II process. Both chips are contained in a single package.
