General Description
The TC7135 4-1/2 digit A/D converter (ADC) offers 50ppm (1 part in 20,000) resolution with a maximum nonlinearity error of 1 count. An auto zero cycle reduces zero error to below 10µV and zero drift to 0.5µV/°C. Source impedance errors are minimized by a 10p A maximum input current. Rollover error is limited to ±1 count. Microprocessor based measurement systems are supported by BUSY, STROBE and RUN/HOLD control signals. Remote data acquisition systems with...
