| Maximum Sample Rate | 192 kHz |
|---|---|
| Dynamic Range (A‑Weighted) | 142 dB |
| THD + N (worst case) | -133 dB |
| Supply Voltage (VDD_CORE) | 3.3 V |
| Supply Voltage (VDD_IO) | 5.0 V or 3.3 V |
| Operating Temperature Range | -40 °C to +105 °C |
| Package | 28‑Lead SSOP |
The device supports up‑sampling ratios of 1:8 and down‑sampling ratios ranging from 7.75:1 to 1:8.
The AD1896 requires a core supply of 3.3 V and an I/O supply of either 5.0 V or 3.3 V.
The AD1896 is available in a 28‑lead SSOP plastic package.
The device achieves a 142 dB A‑Weighted dynamic range at a 44.1 kHz to 48 kHz sample‑rate conversion.
