TLV320AIC23BIPWRCT

Codecs Overview

The TLV320AIC23BIPWRCT is a low-power stereo audio codec manufactured by Texas Instruments, featuring integrated analog-to-digital and digital-to-analog converters. It supports sampling rates from 8 kHz to 96 kHz with resolutions of 16, 20, 24, or 32 bits. The device includes a stereo headphone amplifier capable of driving loads down to 32 ohms. Digital interfaces include I²C and SPI for control, while audio data utilizes standard formats like I²S. Power supply requirements are 2.7 V to 3.6 V for analog/digital sections and 1.42 V to 3.6 V for the headphone amp. The component operates within a temperature range of -40°C to +85°C and is housed in a 28-pin TSSOP package.

Codecs Procurement Notes

Verify the specific suffix 'CT' against official Texas Instruments documentation to confirm tape-and-reel packaging specifications and moisture sensitivity levels. Confirm current production status as this series may be discontinued or superseded by newer revisions. Ensure compatibility with existing board layouts when sourcing replacements.

Codecs Selection Notes

Select this component for designs requiring a single-chip solution for stereo audio input and output. Verify that the host processor supports the required serial clock frequencies and interface protocols. Consider the thermal performance of the TSSOP-28 package if operating near maximum temperature limits. Check power budget constraints against the specified active and standby current consumption values.

Codecs Part Context

This part belongs to the TLV320AIC23B family of audio codecs. It serves as a direct successor to earlier generations, offering improved power efficiency and integration. The 'B' designation typically indicates an enhanced version with optimized performance characteristics compared to the base model. It is designed for consumer electronics where space and power are critical constraints.

Codecs Replacement Considerations

Direct pin-compatible alternatives include the TLV320AIC23BIPW and TLV320AIC23BIPWR. Verify that any substitute maintains the same voltage ranges and interface timing requirements. Cross-reference datasheets to ensure identical register maps if software migration is not planned.
