OUT (pk-pk) = ± 3 V
3SNR calculation includes distortion and noise components.
4Using external sample-and-hold (see Testing the AD7840).
5Measured with respect to REF IN and includes bipolar offset error.
6For capacitive loads greater than 50 pF, a series resistor is required (see Internal Reference section).
7Sample tested @ +25
°C to ensure compliance.
