TC835CBU 64-Pin PQFP 0 °C to +70 °C TC835CKW 44-Pin PQFP 0 °C to +70 °C The TC835 is a low-power,4-1/2 digit (0.005%resolu- tion),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 roll-over error compen- sation circuits required by the ICL7135. The multiplexed BCD data output is perfect for inter- facing 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,under- range,busy,and run/hold control functions and multi- plexed BCD data outputs make the TC835 the ideal converter for µP-based scales and 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.
