1 Measured with a low input frequency, full-scale sine wave.
2 Input capacitance refers to the effective capacitance between one differential input pin and its complement.
3 Input resistance refers to the effective resistance between one differential input pin and its complement.
4 Standby power is measured with a dc input and the CLK± pin active.
