Product details
Overview
TLV320AIC24IPFB-1 from Texas Instruments is a low-power, dual-channel 16-bit sigma-delta audio codec optimized for voice-band applications. It integrates stereo ADC/DAC paths, programmable PGA (±42 dB gain), on-chip FIR/IIR filters, analog sidetone, and multiple output drivers (line, headset, handset). It operates at up to 26 kSPS with IIR/FIR enabled or 104 kSPS in bypass mode, supporting 8-Ω speaker drive (AIC20/21 only) and 150-Ω headset outputs - deployed in VOIP handsets and wireless accessories.
For engineers reviewing the TLV320AIC24IPFB-1 datasheet, TLV320AIC24IPFB-1 pinout, TLV320AIC24IPFB-1 application, or TLV320AIC24IPFB-1 equivalent, key selection considerations include its 48-pin TQFP package, SMARTDM™ serial interface compatibility with TMS320C5000/C6000 DSPs, independent ADC/DAC power-down control, and differential analog I/O architecture with 84 dB SNR (ADC) and 92 dB SNR (DAC) over 13 kHz bandwidth.
Technical Context
The TLV320AIC24IPFB-1 implements two independent sigma-delta conversion channels with decimation/interpolation filtering, configurable FIR/IIR digital filters (bypassable), and analog sidetone mixing. Its SMARTDM™ serial port supports glueless 4-wire TDM interface to TI DSPs, with automatic cascade detection enabling up to eight devices per bus.
It features dual programmable analog front-ends: microphone input with MICBIAS, line/headset/handset inputs with selectable gain, and dedicated differential outputs - LINEO± (600 Ω), HDSO±/HNSO± (150 Ω), and SPKO± (8 Ω, not supported on AIC24). Host configuration uses 2-wire I²C/S2C interface with SDA/SCL pins.

FAQ
What is the maximum sampling rate supported by the TLV320AIC24IPFB-1 with digital filters enabled?
The TLV320AIC24IPFB-1 supports a maximum sampling rate of 26 kSPS when the on-chip FIR or IIR digital filters are active. This rate is derived from the master clock (MCLK) using the coarse sampling configuration (P = 8), ensuring compliance with telephony standards like G.711. The TLV320AIC24IPFB-1 maintains full 16-bit resolution and specified SNR performance at this rate.
Does the TLV320AIC24IPFB-1 include an integrated 8-Ω speaker driver?
No, the TLV320AIC24IPFB-1 does not include an integrated 8-Ω speaker driver. That feature is exclusive to the TLV320AIC20 and TLV320AIC21 variants. The TLV320AIC24IPFB-1 provides differential outputs for line (600 Ω), headset (150 Ω), and handset (150 Ω) loads only - confirmed in TI SLAS363D Section 7.2 and functional block diagrams.
How does the SMARTDM™ interface of the TLV320AIC24IPFB-1 differ from standard I²S?
The SMARTDM™ interface in the TLV320AIC24IPFB-1 is a TI-proprietary synchronous 4-wire TDM protocol supporting glueless connection to TMS320C5000/C6000 DSPs. Unlike I²S, it includes automatic cascade detection (ACD), continuous data transfer mode, turbo mode for bit-clock optimization, and native support for up to eight devices on a single serial bus - all without external logic.
Can the TLV320AIC24IPFB-1 operate with a 1.8 V digital core supply and 3.3 V analog supply simultaneously?
Yes, the TLV320AIC24IPFB-1 is explicitly designed for split-supply operation: DVDD = 1.65–1.95 V (nominal 1.8 V) for the digital core, and AVDD = 2.7–3.6 V (nominal 3.3 V) for analog circuitry. This separation minimizes digital noise coupling into sensitive analog paths and is validated across all electrical characteristics in the TI datasheet.
What is the function of the PWRDN pin on the TLV320AIC24IPFB-1?
The PWRDN pin on the TLV320AIC24IPFB-1 provides hardware-level power-down control: asserting it low places the device into a deep-sleep state drawing less than 1 µA. This complements software-controlled power-down modes and is used for rapid system-level power gating - distinct from register-based ADC/DAC disable functions.
