AD7472–SPECIFICATIONS
REV. B
Temperature ranges as follows: A and B Versions: –40°C to +85°C.
The AD7472 functionally works at 2.35 V. Typical specifications @ 25°C for SNR (100 kHz) = 68 dB; THD (100 kHz) = –84 dB; INL ± 0.8 LSB.
Sample tested @ 25°C to ensure compliance.
See Power vs. Throughput Rate section.
