PRODUCT DESCRIPTION  
PRODUCT HIGHLIGHTS  
The AD677 is a multipurpose 16-bit serial output analog-to-  
digital converter which utilizes a switched-capacitor/charge  
redistribution architecture to achieve a 100 kSPS conversion  
rate (10 µs total conversion time). Overall performance is opti-  
mized by digitally correcting internal nonlinearities through  
on-chip autocalibration.  
1. Autocalibration provides excellent dc performance while  
eliminating the need for user adjustments or additional exter-  
nal circuitry.  
2. ±5 V to ±10 V input range (±VREF).  
3. Available in 16-pin 0.3" skinny DIP or 28-lead SOIC.  
4. Easy serial interface to standard ADI DSPs.  
5. TTL compatible inputs/outputs.  
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.  
6. Excellent ac performance: –99 dB THD, 92 dB S/(N+D)  
peak spurious –101 dB.  
The AD677 is specified for ac (or “dynamic”) parameters such  
as S/(N+D) Ratio, THD and IMD which are important in sig-  
nal processing applications. In addition, dc parameters are  
specified which are important in measurement applications.  
7. Industry leading dc performance: 1.0 LSB INL, ±1 LSB full  
scale and offset.  
The AD677 operates from +5 V and ±12 V supplies and typi-  
cally consumes 450 mW using a 10 V reference (360 mW with  
5 V reference) during conversion. The digital supply (VDD) is  
separated from the analog supplies (VCC, VEE) for reduced digi-  
tal crosstalk. An analog ground sense is provided to remotely  
sense the ground potential of the signal source. This can be use-  
ful if the signal has to be carried some distance to the A/D con-  
verter. Separate analog and digital grounds are also provided.  
The AD677 is available in a 16-pin narrow plastic DIP, 16-pin  
narrow side-brazed ceramic package, or 28-lead SOIC. A paral-  
lel output version, the AD676, is available in a 28-pin ceramic  
or plastic DIP. All models operate over a commercial tempera-  
ture range of 0°C to +70°C or an industrial range of –40°C to  
+85°C.
