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 (±V_REF).

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 (V_DD) is

separated from the analog supplies (V_CC, V_EE) 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.
