Four analog input voltage ranges are selectable via user pin
programming: 0V to +5V, 0V to +10V,
5V, and
10V. Unipolar
coding is provided in true binary format with bipolar coding
displayed in offset binary and two's complement. Tri-state buffers
provide easy interface to bus structured applications.

GENERAL DESCRIPTION
The DAS11152/DAS1153 are 14-/15-bit sampling analog-to-digital
converters having a maximum throughput rate of 25kHz/20kHz. They
provide high accuracy, high stability, and functional completeness all
in a 2" x 4" x 0.44" metal case.
Guaranteed high accuracy system performance such as nonlinearity of
0.005% FSR (DAS1152)/
0.003% FSR (DAS1153) and differential
nonlinearity of
0.003% FSR (DAS1152)/
0.002% FSR (DAS1153)
are provided. Guaranteed stability such as differential nonlinearity
T.C. of
2ppm/
C (DAS1153) maximum, zero T.C. of
80
V/
C
maximum, gain T. C. of 8ppm/
C maximum and power supply
sensitivity of 0.001% FSR/% Vs are also provided by the
DAS1152/DAS1153.
The DAS1152/DAS1153 make extensive use of both integrated circuit
and thin film components to obtain their excellent performance, small
size, and low cost. The devices contain a precision sample/hold
amplifier, high accuracy 14-/15-bit analog- to-digital converter, tri-
state output buffers, internal gain and offset trim potentiometers, and
power supply bypass capacitors (as shown in Figure 1).
