TLV320AIC22CPT

TLV320AIC22CPT Description

The TLV320AIC22CPT from Texas Instruments is a dual-channel VOIP CODEC designed for high-quality audio processing in digital communication systems. This 16-bit resolution IC integrates two ADCs and two DACs, delivering a dynamic range of 87 dB (ADCs) and 92 dB (DACs) with signal-to-noise ratios (SNR) of 84 dB (ADCs) and 92 dB (DACs). It operates with dual voltage supplies: 1.65V–1.95V (digital) and 2.7V–3.6V (analog), ensuring compatibility with low-power and mixed-signal designs. The device uses a serial data interface and Sigma-Delta modulation for superior audio fidelity. Packaged in a 48-LQFP and RoHS3-compliant, it is suited for surface-mount applications but is marked as "Not For New Designs", indicating legacy status.
