The Microchip Technology TC7135CPI is a 4-1/2 digit Analog to Digital Converter (ADC) offering high precision for DC measurements and sensor interfaces. It boasts a resolution of 50 ppm (1 part in 20,000) with a maximum nonlinearity error of ±1 count and a low rollover error of ±1 count.
This ADC provides true polarity indication at zero for null detection and features multiplexed BCD data output. Its TTL-compatible outputs and control signals allow for easy interfacing with UARTs and microprocessors. The TC7135CPI also supports auto-ranging with dedicated overrange and underrange signals, and a blinking display visually indicates overrange conditions.
Designed for applications requiring precision analog signal processing, the TC7135CPI minimizes source impedance errors with a low input current of 1 pA and low zero reading drift of 2 µV/°C. It is available in PDIP and surface-mount packages, including PLCC and MQFP.
Key electrical characteristics include a clock input frequency of 120 kHz and an auto-zero cycle that reduces zero error to below 10 µV. The device is suitable for microprocessor-based measurement systems and remote data acquisition systems.
