PRODUCT DESCRIPTION
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
s total conversion time). Overall performance is opti-
mized by digitally correcting internal nonlinearities through
on-chip autocalibration.
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.
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.
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.
