32-PIN CERAMIC DIP PACKAGE
DESCRIPTION
The ADC601 is a high-speed Duolithic™ (two chips)
successive approximation analog-to-digital converter.
This unique two-chip design utilizes a bipolar technol-
ogy with on-chip thin film resistors to preserve analog
accuracy and a high-speed CMOS chip to perform
digital logic control. Outstanding linearity, noise, and
dynamic range are achieved by this converter design.
The ADC601 has been tested with several sample/hold
amplifiers and distortion results are documented in this
data sheet.
The ADC601 is complete with internal reference, clock,
and comparator and is packaged in a 32-pin ceramic
DIP. Conversion time is set at the factory to 900ns.
Serial and parallel output performance is guaranteed
with no missing codes over the full input voltage,
power supply, and operating temperature range. The
gain and offset errors are laser trimmed to specifica-
tion. Optionally they may be externally adjusted to
zero.
Internal scaling resistors are provided for the selection
of analog signal input ranges of
±5V, ±10V
and 0V to
–10V. The ADC601’s input is specifically designed to
be easily driven with minimal disturbance to the driv-
ing amplifier.
Output codes are available in complementary binary
for unipolar inputs and bipolar offset binary for bipolar
inputs.
All digital inputs and outputs are TTL-compatible.
Power supply requirements are
±15V
and +5V.
