AD7470–SPECIFICATIONS
Temperature ranges as follows: A Version: –40°C to +85°C.
The AD7470 functionally works at 2.35 V. Typical specifications @ 25°C for SNR (100 kHz) = 59 dB; THD (100 kHz) = –84 dB; INL ± 0.8 LSB.
The AD7470 will typically maintain A-grade performance up to 125°C, with a reduced CLK of 20 MHz @ 5 V and 16 MHz @ 3 V. Typical sleep mode current @ 125°C is 700 nA.
Sample tested @ 25°C to ensure compliance.
