TC7135 Datasheet (Microchip) - 4-1/2 Digit A/D Converter

TC7135, 4-1/2 Digit A/D Converter

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 10pA maximum input current.

Rollover error is
