Analog Devices AD676
The AD676 is a multipurpose 16-bit parallel 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 AD676 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.- Min Voltage : 4.5V
- Max Voltage : 12.6V
- Channels : 1
- Max Operating Temp : 70°C
- Min Operating Temp : 0°C

CLK 10 Overall performance is optimized by digitally correcting internal nonlinearities through on-chip autocalibration. Both chips are contained in a single package. The AD676 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. AD676 The AD676 operates from +5 V and ± 12 V supplies and typically consumes 360 mW during conversion. The digital supply (VDD) is separated from the analog supplies (VCC, VEE) for reduced digital crosstalk.
