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 stab ility, 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 ±80µV/°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 contai n a precision sample/hold
amplifier, high accuracy 14-/15-bit an al og- to-digital converter, tri-
state output buffers, intern al gain and offset trim poten tiometers, and
power supply bypass capacitors (as shown in Figure 1).
