TLC1225IN

Analog To Digital Converters (ADC) Overview

The TLC1225IN is a 12-bit analog-to-digital converter manufactured by Texas Instruments. It utilizes a Successive Approximation Register (SAR) architecture to provide high-resolution data conversion. The device features a single channel with parallel word access, allowing for efficient data transfer in systems requiring direct bus interfacing. Packaged in a 28-pin PDIP format, it supports CMOS logic levels and includes self-calibration capabilities to maintain accuracy over time and temperature variations.

• Embedded sensor interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify the package type matches the required PCB footprint, specifically confirming the 28-pin PDIP configuration. Ensure the design supports parallel data bus connections rather than serial protocols. Check that the system voltage levels are compatible with the CMOS input requirements of the component.

Analog To Digital Converters (ADC) Selection Notes

Choose this component when a parallel interface is preferred over serial options like SPI or I2C. It is suitable for applications requiring 12-bit resolution where direct bus access simplifies software timing. Consider the physical size constraints of the 28-pin DIP package during layout planning.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments family of successive approximation ADCs. It differs from other series members by offering parallel access instead of serial communication. The inclusion of self-calibration distinguishes it from basic SAR converters, providing enhanced accuracy without external calibration routines.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes may include other 12-bit parallel SAR ADCs from Texas Instruments. Verify pin compatibility and interface protocol before swapping. Alternative manufacturers may offer similar specifications but require careful validation of electrical characteristics.
