TC7109CPL

The TC7109CPL is a 12-bit analog-to-digital converter (ADC) from Microchip Technology (formerly Telcom Semiconductor). It features dual-slope integration for high accuracy, low noise, and excellent rejection of 50/60Hz interference.
Key specifications:
- Resolution: 12 bits (±1 LSB max error).
- Inputs: Differential, with auto-zero for drift correction.
- Output: 12-bit parallel binary (with polarity and overrange signals).
- Reference: On-chip or external (200mV–3V range).
- Power Supply: ±5V for analog, +5V for digital.
Commonly used in precision measurement systems, such as digital multimeters and industrial instruments, due to its stability and noise immunity. The TC7109CPL interfaces easily with microcontrollers via its parallel output.
For detailed operation, refer to the datasheet for timing, calibration, and application notes.
