Upgrade of Pin-Compatible TC7135, ICL7135
200 kHz Operation
Single 5V Operation With TC7660
Multiplexed BCD Data Output
UART and Microprocessor Interface
Control Outputs for Auto-Ranging
Input Sensitivity: 100 μV
No Sample and Hold Required
The TC835 is a low power, 4-1/2 digit (0.005%
resolution), BCD analog-to-digital converter (ADC) that
has been characterized for 200 kHz clock rate
operation. 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 resistor 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 μV 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 micro-
processor-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.
