ADCs/DACs - Special Purpose datasheet and documents for TC7106CKW

TC7106CKW

ADCs/DACs - Special Purpose Overview

The TC7106CKW is a 3-1/2 digit dual-slope Analog-to-Digital Converter (ADC) manufactured by Microchip Technology. It features an internal precision voltage reference with a typical temperature coefficient of 80 ppm/°C and operates on a single 9V supply. The device provides high-impedance differential inputs with 10^12 Ω impedance and 1 pA leakage current. Key electrical specifications include a peak-to-peak noise of 15 µV, linearity error within ±1 count, and a conversion rate of 3 conversions per second at a 48 kHz clock frequency. It is housed in a 44-pin MQFP package.

ADCs/DACs - Special Purpose Feature Summary

Internal low-drift voltage reference (80 ppm/°C typical)
Direct drive capability for LCD displays
High input impedance: 10^12 Ω with 1 pA leakage
Auto-zero cycle eliminates zero adjustment requirements

ADCs/DACs - Special Purpose Applications

Thermometry
Bridge readouts including strain gauges and load cells
Digital meters for voltage, current, ohms, and power
Portable instrumentation powered by 9V batteries

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'KW' corresponds to the 44-pin MQFP plastic package when sourcing. Confirm the commercial temperature range (0°C to +70°C) aligns with system requirements. Ensure external passive components match the recommended values for the desired full-scale voltage to maintain specified accuracy.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring direct LCD interfacing without additional driver logic. The TC7106A variant offers improved reference drift (20 ppm/°C) compared to the standard TC7106. Ensure the application utilizes a 9V battery or compatible supply, as the device is optimized for this voltage range. Verify that the 3 readings per second speed meets the data acquisition needs.

ADCs/DACs - Special Purpose Part Context

The TC7106CKW belongs to the TC7106/A family of integrating ADCs. It serves as a drop-in replacement for earlier TC7106 designs, allowing upgrades to systems with better temperature stability without changing external passive component values. It is distinct from the TC7107 series, which drives LED displays directly.
