TC7106CLW713

ADCs/DACs - Special Purpose Overview

The TC7106CLW713 is a low-power, 3-1/2 digit Analog-to-Digital Converter (ADC) manufactured by Microchip Technology. It features a dual-slope integrating architecture with a direct LCD drive capability and a 44-pin PLCC package. The device incorporates an internal precision reference with a typical temperature drift of 80 ppm/°C. Key electrical specifications include a peak-to-peak noise level of 15 µV, high-impedance CMOS differential inputs with 1 pA leakage current, and a conversion rate of 3 readings per second at a 48 kHz clock frequency. It operates on a single supply voltage ranging from 2.7 V to 5 V.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix '713' against official Microchip documentation to confirm packaging details such as tube quantity or reel specifications. Ensure the component meets RoHS compliance requirements if applicable to the target assembly process. Cross-reference the datasheet revision DS21455D for any updates regarding absolute maximum ratings or thermal dissipation limits.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a direct LCD interface is required without external decoding logic. The TC7106CLW713 is suitable for applications needing ratiometric measurements using differential reference inputs. For improved temperature stability compared to standard versions, consider the TC7106A variant which offers a lower 20 ppm/°C drift. Ensure the application environment stays within the commercial operating temperature range of 0°C to +70°C.

ADCs/DACs - Special Purpose Part Context

This part belongs to the TC7106/A/TC7107/A family of 3-1/2 digit ADCs. The TC7106 series specifically targets LCD display applications, whereas the TC7107 series drives LEDs. The TC7106CLW713 represents the commercial grade version in a 44-pin Plastic Leadless Chip Carrier (PLCC) package. It serves as a drop-in replacement for legacy TC7106 designs while offering enhanced linearity and reduced rollover error.

ADCs/DACs - Special Purpose Replacement Considerations

The TC7106CLW is a direct functional equivalent to the TC7106ACLW. Both share identical pinouts and electrical characteristics for the base model. Verify that the specific '713' suffix does not denote a non-standard packaging variation that requires board layout adjustments.
