TC835  
Personal Computer Data Acquisition A/D Converter  
Features  
General Description  
• Upgrade of Pin-Compatible TC7135, ICL7135  
• 200kHz Operation  
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.  
• Single 5V Operation With TC7660  
• Multiplexed BCD Data Output  
• UART and Microprocessor Interface  
• Control Outputs for Auto-Ranging  
• Input Sensitivity: 100µV  
• No Sample and Hold Required  
The multiplexed BCD data output is perfect for interfac-  
ing to personal computers. The low cost, greater than  
14-bit high-resolution and 100µV sensitivity makes the  
TC835 exceptionally cost-effective.  
Applications  
• Personal Computer Data Acquisition  
• Scales, Panel Meters, Process Controls  
• HP-IL Bus Instrumentation  
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 µP-  
based scales, measurement systems and intelligent  
panel meters.
