TLC320AC02IFNR

Codecs Overview

The TLC320AC02IFNR is a single-supply analog interface circuit (AIC) manufactured by Texas Instruments. It integrates a 14-bit resolution analog-to-digital converter (ADC) and a 14-bit digital-to-analog converter (DAC). The device operates on a single 5-V power supply with a minimum voltage of 4.5 V and a maximum of 5.5 V. It supports a conversion rate up to 25 kHz for the DAC channel. The component utilizes a serial interface for data and control transfers, featuring programmable filter bandwidths up to 10.8 kHz. It is housed in a PLCC-28 package and functions within an operating temperature range of -40°C to +85°C.

Codecs Feature Summary

• Integrates band-pass switched-capacitor antialiasing input filter and low-pass output-reconstruction filter with (sin x)/x compensation
• Supports stand-alone, master-slave, and linear-codec modes of operation via serial port interface
• Features differential architecture throughout with programmable gains for inputs, outputs, and monitor signals

Codecs Applications

• Modems
• Speech processing systems
• Analog interfaces for DSPs
• Industrial process control
• Acoustical signal processing

Codecs Procurement Notes

Verify the specific suffix IFNR corresponds to the PLCC-28 package and industrial temperature grade (-40°C to +85°C) as defined in the official datasheet. Confirm that the ordering information matches the manufacturer's current product release notes to ensure compatibility with system requirements.

Codecs Selection Notes

Select this component when a monolithic solution for audio-band processing is required. Ensure the application supports a single 5-V supply and requires 14-bit resolution. Verify that the serial interface timing aligns with the host processor's capabilities for master or slave mode operation.

Codecs Part Context

This part belongs to the TLC320AC02 family of analog interface circuits. It is functionally equivalent to the TLC320AC01 but differs in electrical specifications. The 'I' designation indicates the industrial temperature range variant, while 'FN' specifies the plastic leaded chip carrier package type.

Codecs Replacement Considerations

The TLC320AC01 is functionally equivalent but has different electrical specifications. Verify pinout and register compatibility before substitution.
