MICROCHIP TC7129 Manual
Update: 30 September, 2023
The TC7129 is a 4-1/2-digit analog-to-digital converter (ADC) from Microchip that directly drives a multiplexed liquid crystal display (LCD). It is fabricated in high-performance, low-power CMOS and is specifically designed for high-resolution, battery-powered digital multimeter applications. The traditional dual-slope method of A/D conversion has been enhanced with a successive integration technique to produce readings accurate to better than 0.005% of full scale and resolution down to 10µV per count. The TC7129 includes features important to multimeter applications. It detects and indicates low battery condition. A continuity output drives an annunciator on the display and can be used with an external driver to sound an audible alarm. Over range and under range outputs and a range change input provide the ability to create auto-ranging instruments. For snapshot readings, the TC7129 includes a latch-and-hold input to capture a reading in the event of an overvoltage or undervoltage.
