Overview
The TLV320AIC23IGQER, manufactured by Texas Instruments, is a high-performance stereo audio codec designed for portable audio applications. This integrated circuit (IC) features a built-in headphone amplifier and supports both microphone and line-in inputs with programmable gain control. Its advanced Σ-Δ oversampling technology enables high-quality audio conversion with sampling rates ranging from 8 kHz to 96 kHz and resolutions of 16-bit, 20-bit, 24-bit, and 32-bit. With an ADC signal-to-noise ratio (SNR) of 90 dB and a DAC SNR of 100 dB, the TLV320AIC23IGQER delivers exceptional audio fidelity. Its low power consumption (23 mW in playback mode and 15 μW in power-down mode) makes it an ideal choice for battery-powered devices. This codec is particularly well-suited for applications requiring high-quality audio processing, such as portable media players, smartphones, and audio interfaces.
