stability over commercial (0°C to +70°C) temperature ranges
(for extended temperature ranges, the pin compatible AD1378
is recommended.) T ypical applications include medical and
analytic instrumentation, precision measurement for industrial
robotics, automatic test equipment (AT E), and multichannel
data acquisition systems, servo control systems or anywhere
wide dynamic range is required A proprietary monolithic DAC
and laser-trimmed thin-film resistors guarantee a maximum
nonlinearity of ±0 003% (1/2 LSB14.) T he converters may be
short cycled to achieve faster conversion times – 15 µs to 14 bits
for the AD1376, or 8 µs to 14 bits for the AD1377.

T he AD1376/AD1377 are high resolution, 16-bit analog-to-
digital converters with internal reference, clock and laser-trim-
med thin-film applications resistors. T hey are packaged in a
compact 32-pin, ceramic scam sealed (hermetic) dual-in-line
packages (DIP). T hin-film scaling resistors provide bipolar
input ranges of ±2.5 V, ±5 V, ±10 V and unipolar input ranges
of 0 V to +5 V, 0 V to +10 V and 0 V to +20 V.
2. AD1376 conversion time is 14 µs (typical) short cycled to 14
bits, and 16 µs to 16 bits.
3. AD1377 conversion time is 8 µs (typical) short cycled to 14
bits, and 9 µs to 16 bits.
4. T wo binary codes are available on the digital output. T hey are
CSB (Complementary Straight Binary) for unipolar input
voltage ranges and COB (Complementary Offset Binary) for
bipolar input ranges. Complementary T wos Complement
(CT C) coding may be obtained by inverting Pin 1 (MSB).
Digital output data is provided in parallel and serial form with
corresponding clock and status outputs. All digital inputs and
outputs are T T L compatible.
5. T he AD1376 and AD1377 include internal reference and
clock, with external clock rate adjust pin, and serial and paral-
lel digital outputs.
AP P LICATIO NS
T he AD1376/AD1377 are excellent for use in high resolution
applications requiring moderate speed and high accuracy or
