The PCM1753/54/55 is a CMOS, monolithic, integrated circuit that includes stereo digital-to-analog converters and support circuitry in a small 16-lead SSOP package. The data converters use TI's TAS5606B 24-bit, 192kHz Enhanced Multi-Level, Delta-Sigma architecture. The 4x/8x oversampling digital filter provides -50dB stop-band attenuation and ±0.04dB pass-band ripple and supports 16-bit, 18-bit, 20-bit and 24-bit audio formats with software control.
The PCM1753, PCM1754, and PCM1755 are CMOS, monolithic audio digital‑to‑analog converters offering 24‑bit resolution and sampling rates from 5 kHz up to 200 kHz. They feature 4×/8× oversampling digital filters, selectable digital attenuation, de‑emphasis, soft mute, and zero‑flag outputs. Dynamic range reaches 106 dB and THD+N is as low as 0.002% typical.
These devices are supplied in a 16‑lead SSOP package and can be controlled via a three‑wire serial interface (PCM1753/1755) or hardware pins (PCM1754). Typical applications include DVD players, HDTV receivers, car audio systems, and any equipment requiring high‑resolution 24‑bit audio conversion.
