AD1852 is a high-performance audio DAC launched by Analog Devices. It supports 24-bit, 192kHz sampling rate, supports 16-bit/18-bit/20-bit/24-bit data, has perfect differential linearity restoration function, can reduce idle tones and noise floor noise, minimize jitter, and has 117dB signal-to-noise ratio (not muted), 114dB dynamic range (not muted), -105dB THD+N (mono application circuit), -102dB THD+N (stereo application circuit) and other features.
The AD1852 Rev. A is a single‑chip, stereo digital‑audio playback system that integrates a multibit Σ‑Δ modulator, digital interpolation filters, and differential analog output drivers. It operates from a single 5 V supply and supports 16‑, 18‑, 20‑, and 24‑bit audio data in several serial formats.
The datasheet provides detailed specifications such as 112 dB SNR (stereo, no filter), 107 dB dynamic range, and low THD+N. Pin‑out, timing diagrams, power consumption, and typical performance graphs are included, along with ordering information for the SSOP‑28 package.
| Supply Voltage (AVDD, DVDD) | 5.0 V |
|---|---|
| Signal‑to‑Noise Ratio (Stereo, No Filter) | 112 dB |
| Analog Power Consumption | 165 mW |
The device is rated for a supply voltage of 5.0 V (AVDD, DVDD) and absolute maximum ratings of –0.3 V to +6 V.
It uses an SPI‑compatible serial control port and can accept audio data in right‑justified, I²S, left‑justified, or DSP formats.
The differential output range is ±5.6 V peak‑to‑peak.
