Overview
The TLV320AIC24IPFB-1 is a low-power, highly integrated, dual-channel audio CODEC manufactured by Texas Instruments. It features two 16-bit oversampling sigma-delta analog-to-digital converters (ADCs) and two 16-bit digital-to-analog converters (DACs). The device supports a maximum sampling rate of 26 kSPS with on-chip IIR/FIR filters enabled, or up to 104 kSPS when the filters are bypassed. It operates with a digital core voltage range of 1.65 V to 1.95 V and an analog supply voltage range of 2.7 V to 3.6 V. The component utilizes a SMARTDM serial port for DSP interfacing and includes programmable gain amplifiers, microphone bias, and sidetone control.
Feature Summary
- Integrates stereo 16-bit oversampling sigma-delta ADCs and DACs with selectable FIR/IIR filters.
- Features a Smart Time Division Multiplexed (SMARTDM) serial port for glueless connection to TI DSPs.
- Includes built-in analog functions such as microphone preamplifiers, handset/headset amplifiers, and programmable gain stages.
- Supports flexible power management with hardware and software-controlled power-down modes.
Applications
- Wireless accessories
- Hands-free car kits
- VOIP systems
- Speech processing
Procurement Notes
Verify the specific ordering suffix 'IPFB-1' against the official Texas Instruments datasheet SLAS363D. The standard commercial grade part is designated as TLV320AIC24IPFB. Confirm that the '-1' suffix does not indicate a non-standard variant or a specific tape-and-reel configuration change that affects electrical characteristics or package dimensions before finalizing procurement.
Selection Notes
Select this component for applications requiring low-power voice-band signal conversion with minimal external components. Ensure the host processor supports the SMARTDM serial interface or can be configured for standard 4-wire synchronous communication. Verify that the system power supplies align with the specified 1.8 V digital core and 3.3 V analog domains. Consider the thermal performance in the 48-TQFP package if operating at maximum sampling rates with all drivers active.
Part Context
The TLV320AIC24 belongs to the TLV320AIC2x family of audio CODECs from Texas Instruments. This family shares common architectural features, including the SMARTDM interface and sigma-delta conversion technology. Variants within the series, such as the AIC20 and AIC21, may differ in output driver capabilities, such as the inclusion of an 8-ohm speaker driver in the AIC20/21 models compared to the line-level outputs of the AIC24.
Replacement Considerations
The TLV320AIC24KFBR is a compatible industrial-grade alternative within the same family, characterized for operation from -40°C to 85°C. Other members of the TLV320AIC2x series, such as the TLV320AIC20 or TLV320AIC25, share pinouts and interfaces but may have different output driver specifications or temperature ranges.
