General Description
The TC835 is a low power, 4-1/2 digit (0.005%
resolution), BCD analog to digital converter (ADC) that
has been characterized for 200kHz clock rate opera-
tion. The five conversions per second rate is nearly
twice as fast as the ICL7135 or TC7135. The TC835,
like the TC7135, does not use the external diode resis-
tor rollover error compensation circuits required by the
ICL7135.
The multiplexed BCD data output is perfect for interfac-
ing to personal computers. The low cost, greater than
14-bit high-resolution and 100
V sensitivity makes the
TC835 exceptionally cost-effective.
Microprocessor-based data acquisition systems are
supported by the BUSY and STROBE outputs, along
with the RUN/HOLD
input of the
TC835. The
OVERRANGE, UNDERRANGE, BUSY and RUN/
HOLD control functions, plus multiplexed BCD data
outputs, make the TC835 the ideal converter for
P-
based scales, measurement systems and intelligent
panel meters.
The TC835 interfaces with full function LCD and LED
display decoder/drivers. The UNDERRANGE and
OVERRANGE outputs may be used to implement an
auto-ranging scheme or special display functions.
