PRODUCT DESCRIPTION
The AD1674 is a complete, multipurpose, 12-bit analog-to-
digital converter, consisting of a user-transparent onboard
sample-and-hold amplifier (SHA), 10 volt reference, clock and
three-state output buffers for microprocessor interface.
The AD1674 is pin compatible with the industry standard
AD574A and AD674A, but includes a sampling function while
delivering a faster conversion rate. The on-chip SHA has a wide
input bandwidth supporting 12-bit accuracy over the full
Nyquist bandwidth of the converter.
The AD1674 is fully specified for ac parameters (such as S/(N+D)
ratio, THD, and IMD) and dc parameters (offset, full-scale
error, etc.). With both ac and dc specifications, the AD1674 is
ideal for use in signal processing and traditional dc measure-
ment applications.
The AD1674 design is implemented using Analog Devices’
BiMOS II process allowing high performance bipolar analog cir-
cuitry to be combined on the same die with digital CMOS logic.
Five different temperature grades are available. The AD1674J
and K grades are specified for operation over the 0
°C to +70°C
temperature range. The A and B grades are specified from
–40
°C to +85°C; the AD1674T grade is specified from –55°C
to +125
°C. The J and K grades are available in both 28-lead
plastic DIP and SOIC. The A and B grade devices are available
in 28-lead hermetically sealed ceramic DIP and 28-lead SOIC.
The T grade is available in 28-lead hermetically sealed ceramic
DIP.

PRODUCT HIGHLIGHTS
1. Industry Standard Pinout: The AD1674 utilizes the pinout
established by the industry standard AD574A and AD674A.
2. Integrated SHA: The AD1674 has an integrated SHA which
supports the full Nyquist bandwidth of the converter. The
SHA function is transparent to the user; no wait-states are
needed for SHA acquisition.
3. DC and AC Specified: In addition to traditional dc specifica-
tions, the AD1674 is also fully specified for frequency do-
main ac parameters such as total harmonic distortion,
signal-to-noise ratio and input bandwidth. These parameters
can be tested and guaranteed as a result of the onboard
SHA.
4. Analog Operation: The precision, laser-trimmed scaling and
bipolar offset resistors provide four calibrated ranges:
0 V to +10 V and 0 V to +20 V unipolar, –5 V to +5 V and
–10 V to +10 V bipolar. The AD1674 operates on +5 V and
±12 V or ±15 V power supplies.
5. Flexible Digital Interface: On-chip multiple-mode
three-state output buffers and interface logic allow direct
connection to most microprocessors.
