The PCM1789PWRG4 is a high-performance, 24-bit stereo digital-to-analog converter (DAC) from Texas Instruments, featuring an enhanced multi-level delta-sigma modulator. It supports a wide sampling rate range from 8 kHz to 192 kHz, making it suitable for various audio applications including Blu-ray and DVD players, AV receivers, and home theaters. The device offers a signal-to-noise ratio (SNR) of 113 dB and total harmonic distortion plus noise (THD+N) of -94 dB, ensuring high audio fidelity. This DAC provides differential voltage outputs of up to 8 VPP and includes an integrated analog low-pass filter. It features a flexible audio interface that supports multiple formats such as I¬=S, left-justified, right-justified, and DSP formats, with data lengths of 16, 20, 24, and 32 bits. The PCM1789 can be controlled via a three-wire SPI or a two-wire I¬=C interface, allowing for functions like digital attenuation and soft mute. The device operates with dual power supplies, requiring 5 V for analog and 3.3 V for digital components, and is housed in a compact 24-pin TSSOP package. It is rated for an operating temperature range of -40¬8C to 85¬8C, making it suitable for a variety of environments.
