The TC7106IPL from Microchip Technology is a highly integrated 3½ digit Analog-to-Digital Converter (ADC) that combines precision analog components with digital logic to offer a complete, compact solution for analog data display. This innovative device is designed to interface directly with a liquid crystal display (LCD), making it an ideal choice for applications requiring a high-resolution readout such as handheld meters, multimeters, and other instrumentation devices.

Key Features

• High Integration: Integrates on-chip: a seven-segment decoder, display drivers, a reference, and a clock.
• Low Power: Designed for battery-operated equipment with a typical power consumption of only 10μW.
• Direct LCD Drive: Capable of driving a 3½ digit, 7-segment, liquid crystal display without requiring additional drivers.
• Auto-Zero: Ensures zero reading for 0 volts input.
• True Differential Input and Reference: Ideal for ratiometric measurements, such as battery-powered scales and other portable applications.
• Polarity and Overrange Indication: Provides visual feedback for signal polarity and measurement range exceedance.
• Internal Oscillator: No external clock is necessary; simplifies design and reduces component count.
