Measured with a low input frequency, full-scale sine wave, with approximately 5 pF loading on each output bit.

2

Input capacitance refers to the effective capacitance between one differential input pin and AGND.

3

Standby power is measured with a dc input and with the CLK± pins active (1.8 V CMOS mode).

AC SPECIFICATIONS

AVDD = 1.8 V, DRVDD = 1.8 V, maximum sample rate, VIN = −1.0 dBFS differential input, 1.0 V internal reference, DCS enabled, unless

otherwise noted.
