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.
