ADC-674

12-Bit, μP-Compatible A/D Converter

PRODUCT OVERVIEW

The ADC-674 A/D converters are available in

both ceramic leadless chip carrier and industry

standard DIP packages.

These units include a reference, clock, three-

state outputs, and digital interface circuit which

allows direct connection to the microprocessor

address bus and control lines. The ADC-674 com-

pletes a 12-bit conversion in 8 microseconds.

Four user selectable input ranges are provided:

0 to +10V, 0 to +20V, +/-5V, and +/-10V dc. Laser

trimming ensures speciﬁed linearity, gain and

offset accuracy.
