TC7126CPL Description

Short technical summary and product information.

The TC7126CPL from Microchip Technology is a 3-1/2 digit CMOS Analog-to-Digital Converter (ADC) that integrates all necessary components for a 0.05% resolution measurement system. It includes seven-segment decoders, digit and polarity drivers, a voltage reference, and a clock circuit on a single chip, directly driving a Liquid Crystal Display (LCD).

 

Key electrical specifications include a typical internal reference temperature drift of 35ppm/°C for the TC7126A variant, low noise of 15 µVP-P, and a low input leakage current of 1pA typical. The device operates conveniently from a 9V battery with low power dissipation, typically 500µW, making it suitable for portable applications.

 

This ADC is designed for applications such as thermometry, bridge readouts (strain gauges, load cells), digital meters (voltage, current, ohms, power, pH), digital scales, and process monitors. Its high-impedance differential inputs offer 1pA leakage current and 10^12 Ohm input impedance. The auto-zero cycle ensures a zero display reading with a 0V input.

 

The TC7126CPL is available in a 40-pin PDIP package and is designed for through-hole mounting. It operates within a temperature range of 0°C to 70°C.
