PRODUCT DESCRIPTION
The ADADC801 is a complete 12-bit successive-approximation
analog-to-digital converter (ADC) that includes an internal
clock, reference, and comparator. Its hybrid IC design uses MSI
digital and linear monolithic chips in conjunction with a 12-bit
monolithic digital-to-analog converter (DAC) to provide
modular performance and versatility with IC size, price, and
reliability.
Important performance characteristics of the ADADC80
include a maximum linearity error of ±0.012% at 25°C,
maximum gain TC of 30 ppm/°C, typical power dissipation of
800 mW, and maximum conversion time of 25 μs. Monotonic
operation of the feedback DAC guarantees no missing codes
over the temperature range of 25°C to +85°C.
The design of the ADADC80 includes scaling resistors that
provide an analog signal range of ±2.5 V, ±5.0 V, ±10 V, 0 V to
+5.0 V, or 0 V to +10.0 V. The 6.3 V precision reference can be
used for external applications. All digital signals are fully DTL
and TTL compatible; output data is in parallel form.
The ADADC80 is available in grades specified for use over the
25°C to +85°C temperature range and is available in a 32-lead
ceramic DIP.
1 The serial output function is no longer supported on this product after
Date Code 9616.
PRODUCT HIGHLIGHTS
1.
The ADADC80 is a complete 12-bit ADC. No external
components are required to perform a conversion.
2.
A monolithic 12-bit feedback DAC is used for reduced chip
count and higher reliability.
3.
The internal buried Zener reference is laser trimmed to
6.3 V. The reference voltage is available externally and can
supply up to 1.5 mA beyond the current required for the
reference and bipolar offset.
4.
The scaling resistors are included on the monolithic DAC
for exceptional thermal tracking.
5.
The ADADC80 directly replaces other devices of this type,
providing significant increases in performance.
6.
The fast conversion rate of the ADADC80 makes it an
excellent choice for applications requiring high system
throughput rates.
7.
The short cycle and external clock options are provided
for applications requiring faster conversion speed or
lower resolution.
