Av is the programmable gain of the input amplifier.
§ Measurements under these conditions are unreliable due to overrange and signal clipping.
NOTE 7: The test condition is a 1-kHz input signal with a 16-kHz conversion rate. The load impedance for the DAC is
600
. Input and output voltages are referred to Vref.
