TC7135 Datasheet (TelCom) - 4-1/2 DIGIT ANALOG-TO-DIGITAL CONVERTER

TC7135, 4-1/2 DIGIT ANALOG-TO-DIGITAL CONVERTER

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.
