Av is the programmable gain of the input amplifier.
All typical values are at TA = 25
°
C.
§A value >58 is overrange and signal clipping occurs.
NOTES:
7. The test condition Vin is a 1-kHz input signal with an 8-kHz conversion rate (0 dB relative to Vref). The load impedance for the DAC
is 600
.
8. Gain tracking is relative to the absolute gain at 1 kHz and 0 dB (0 dB relative to Vref).
