GENERAL DESCRIPTION

The TC7135 4-1/2 digit analog-to-digital converter (ADC) offers 50 ppm (1 part in 20,000) resolution with a maximum nonlinearity error of 1 count. An auto-zero cycle reduces zero error to below 10 μV and zero drift to 0.5 μV/°C. Source impedance errors are minimized by a 10 pA maximum input current. Roll-over error is limited to ±1 count.
