The PCM1851APJT is a high-performance, low-cost stereo analog-to-digital converter (ADC) designed for audio applications. It features a 24-bit delta-sigma architecture with a maximum sampling rate of 96 kHz and supports multiple data formats including left-justified, I¬=S, and right-justified. The device includes a 6-channel single-ended multiplexer and a programmable-gain amplifier (PGA) with a gain range from -11 dB to +11 dB. The PCM1851APJT operates with dual power supplies, requiring 5 V for analog and 3.3 V for digital operations. It is equipped with an on-chip antialiasing filter and a digital decimation filter, ensuring high-quality audio signal processing. Typical specifications include a total harmonic distortion plus noise (THD+N) of 0.0023%, a signal-to-noise ratio (SNR) of 101 dB, and a dynamic range of 102 dB. This ADC is suitable for various cost-sensitive applications such as DVD/CD recorders, AV amplifiers, and multitrack recorders, making it a versatile choice for engineers looking for reliable audio performance in their designs. The device is housed in a compact 32-pin TQFP package, facilitating easy integration into various systems.
