PRODUCT OVERVIEW

contained, high-performance, 12-bit A/D convert-

ers manufactured with thick and thin-ﬁ lm hybrid

technology. They use the successive approximation

conversion technique to achieve a 12-bit conver-

sion in 20 and 8 microseconds, respectively. Five

input voltage ranges are programmable by external

pin connection. An internal buffer ampliﬁ er is also

provided for applications in which 50 megohm

input impedance is required.

DAC which includes a precision zener reference

source. The circuit also contains a fast mono-

lithic comparator, a monolithic 12-bit successive

approximation register, a clock and a monolithic

buffer ampliﬁ er. Nonlinearity is speciﬁ ed at

±1/2LSB maximum.

conversion speed. They can be short-cycled to give

faster conversions in lower-resolution applications.

Use of the internal buffer ampliﬁ er increases con-

version time by 3 microseconds, the settling time

of the ampliﬁ er. Output coding is complementary

binary, complementary offset binary, or comple-

mentary two’s complement. Serial data is also

brought out. The package is a 32-pin ceramic TDIP.

Models are available for use in either commercial

(0 to +70°C) or military (–55 to +125°C) operating

temperature ranges. MIL-STD-883 and DESC Stan-

dard Military Drawing models are also available.
