The SAA7360 is a bitstream conversion ADC for digital audio systems. It features stereo input, single-ended input, uncommitted input buffer for filtering and pre-scaling, fully differential ADC using 3rd order Sigma-Delta modulation, 128 times oversampling, four stage digital decimation filter, switchable high-pass filter to remove DC offsets, selectable 16-bit or 18-bit output, and support for sampling rates between 18kHz and 53kHz.
The SAA7360 is a bitstream conversion CMOS ADC designed for digital audio playback systems such as digital amplifiers, CD‑recordable and DCC devices. It features an input buffer with pre‑scaling and anti‑aliasing, a third‑order sigma‑delta modulator, and a four‑stage digital decimation filter that provides high‑resolution audio conversion.
The device operates from a single +5 V supply, supports master or slave clock modes, and provides selectable 256f (11.2896 MHz) or 512f (22.5792 MHz) crystal frequencies. Output data can be formatted in 16‑bit or 18‑bit word lengths and in three serial interface formats, with a total harmonic distortion plus noise better than 90 dB.
| Supply voltage (Vop) | 4.5 V – 5.5 V |
|---|---|
| Crystal frequency | 256f (11.2896 MHz) or 512f (22.5792 MHz) |
| THD+N | -90 dB to -85 dB |
| Total power consumption | 465 mW |
| Analog supply voltage (Vopa) | 4.5 V – 5.5 V |
| Digital supply voltage (Vppp) | 4.5 V – 5.5 V |
| Operating temperature | -40 °C to +85 °C |
| Storage temperature | -65 °C to +150 °C |
Both the analog and digital supplies operate from 4.5 V to 5.5 V.
It supports either 256f (11.2896 MHz) or 512f (22.5792 MHz).
The device achieves total harmonic distortion plus noise better than 90 dB (typical -85 dB).
