Transforming a simple 10-kΩ NTC thermistor into a precise digital thermometer is a great example of mixed-signal design in action. Using a mixed-signal IC—AnalogPAK SLG47011—this design measures temperatures from 0.1°C to 99.9°C with impressive accuracy and efficiency. SLG47011’s analog-to-digital converter (ADC) with programmable gain amplifier (PGA) captures precise voltage readings, while its memory table and width converter drive a 3-digit dynamic 7-segment display.
This article explores the implementation of a voltmeter using the AnalogPAK SLG47011, featuring a 3-digit, 7-segment dynamic display. The design leverages the device’s ADC with a programmable gain amplifier (PGA) for voltage measurement, while the Memory Table and Width Converter enable dynamic visualization on the display. Depending on the switch position, the voltmeter operates in two selectable voltage ranges — from 9.99 to 99.9 V.
