TLV320AIC24KIPFBR

Overview

The TLV320AIC24KIPFBR is a low-power, highly integrated, dual-channel audio CODEC featuring two 16-bit oversampling sigma-delta analog-to-digital converters and two digital-to-analog converters. It supports a maximum sampling rate of 26 ksps with on-chip filters or 104 ksps when bypassed. The device operates with a digital core voltage of 1.65 V to 1.95 V and an I/O voltage range of 1.1 V to 3.6 V. Analog supplies require 2.7 V to 3.6 V. It achieves an ADC signal-to-noise ratio of 84 dB and a DAC SNR of 92 dB over a 13-kHz bandwidth. The component is housed in a 48-TQFP package and is characterized for industrial operation from -40°C to 85°C.

Feature Summary

• Integrates programmable gain amplifiers, microphone bias, and selectable FIR/IIR filters for voice-band applications.
• Supports SMARTDM serial port for glueless interface to DSPs and flexible 2-wire host port control.
• Includes comprehensive power management with hardware and software-controlled power-down modes.

Applications

• Wireless accessories
• Hands-free car kits
• VOIP systems

Procurement Notes

Verify the specific suffix K indicates the industrial temperature grade (-40°C to 85°C) compared to commercial variants. Confirm the PFB designation corresponds to the 48-TQFP package dimensions. Ensure the source document matches the SLAS363D datasheet revision for accurate electrical specifications.

Selection Notes

Select this model for designs requiring industrial temperature stability and high integration. The K suffix denotes the extended temperature range suitable for automotive or harsh environments. Verify that the required sampling rates align with the internal clock generator capabilities and master clock input constraints.

Part Context

This component belongs to the TLV320AIC2x family of low-power audio CODECs. The AIC24 variant specifically excludes the built-in speaker driver found in the AIC20/AIC21 models, focusing on line-level and headset interfaces. The K suffix differentiates it by its industrial operating temperature range.

FAQ

What is the difference between the TLV320AIC24 and TLV320AIC24K?

The primary difference is the operating temperature range. The TLV320AIC24K is characterized for industrial operation from -40°C to 85°C, whereas the standard TLV320AIC24 is typically characterized for commercial operation from 0°C to 70°C.

Does the TLV320AIC24K include a built-in speaker driver?

No, the TLV320AIC24 and TLV320AIC24K do not include a built-in speaker driver. This feature is available only in the TLV320AIC20 and TLV320AIC21 variants within the same family.
