1 Maximum specifications are measured across
40°C to 125°C (case) and across VDD = 2.25 V to 2.75 V.
2 Measurement running a typical large program that writes to all 16 outputs with 0 dB digital sine waves applied to all eight inputs. The end user’s program may differ.
3 The digital reset current is specified for the given test conditions. This current scales with the input MCLK rate, so higher input clocks draw more current while in reset.
