2 SNR specifications in decibels are referred to a full-scale input, FS. Tested with an input signal at 0.5dB below full scale, unless otherwise specified.
3 Output Data Rate (ODR) = [(MCLK/2)]/Decimation Rate. That is, the maximum ODR for AD7765 = [(40 MHz)/2)/128] = 156.25 kHz.
4 Tested with a 400 μA load current.
5 Tested at MCLK = 40 MHz. This current scales linearly with MCLK frequency applied.
6 Tested at 125°C.
