GENERAL DESCRIPTION
The AD1376/AD1377 are high resolution, 16-bit analog-to-
digital converters with internal reference, clock, and laser-
trimmed thin-film applications resistors. The AD1376/AD1377
are excellent for use in high resolution applications requiring
moderate speed and high accuracy or stability over commercial
temperature ranges (0°C to 70°C). They are packaged in
compact 32-lead, ceramic seam-sealed (hermetic), dual in-line
packages (DIP). Thin-film scaling resistors provide bipolar
input ranges of ±2.5 V, ±5 V, and ±10 V and unipolar input
ranges of 0 V to +5 V, 0 V to +10 V, and 0 V to +20 V.

Digital output data is provided in parallel form with
corresponding clock and status outputs. All digital inputs and
outputs are TTL-compatible.
For the AD1376, the serial output function is no longer
available after date code 0111. For the AD1377, the serial output
function is no longer available after date code 0210. The option
of applying an external clock on the CONVERT START pin to
slow down the internally set conversion time is no longer
supported for either part.

The AD1376/AD1377 provide 16-bit resolution with a
maximum linearity error of ±0.003% (1/2 LSB
The AD1376 conversion time is 14 µs (typical) short cycled
to 14 bits, and 16 µs to 16 bits.
The AD1377 conversion time is 8 µs (typical) short cycled
to 14 bits, and 9 µs to 16 bits.
Two binary codes are available on the digital output. They
are CSB (complementary straight binary) for unipolar input
voltage ranges and COB (complementary offset binary) for
bipolar input ranges. Complementary twos complement
(CTC) coding may be obtained by inverting Pin 1 (MSB).
The AD1376/AD1377 include internal reference and clock
with external clock rate adjust pin, and parallel digital outputs.
