TC7129CKW Description

Short technical summary and product information.

The TC7129CKW from Microchip Technology is a 4-1/2 digit Analog-to-Digital Converter (ADC) designed for high-resolution, battery-powered digital multimeter applications. It features a count resolution of ±19,999 and a resolution of 10 µV on the 200 mV scale. The device offers direct LCD driver capability for 4-1/2 digits, decimal points, a low battery indicator, and a continuity indicator.

 

Fabricated in high-performance, low-power CMOS, the TC7129CKW operates with a supply voltage range of 6V to 12V and consumes a typical current of 800 µA. It includes features such as overrange and underrange outputs, and a range-select input for auto-ranging instruments. The device also has a latch-and-hold input for snapshot readings.

 

This component comes in a 44-PQFP (10x10) package and is suitable for surface mount applications. It operates within a temperature range of 0°C to 70°C. The TC7129CKW is ideal for full-featured multimeter and digital measurement devices.
