1 See the Terminology section.

2 SNR specifications in decibels are referred to a full-scale input, FS. Tested with an input signal at 0.5 dB below full scale, unless otherwise specified.

3 Current scales with ICLK frequency. See the Typical Performance Characteristics section.

4 Although the AD7760 can function with an MCLK amplitude of less than 5 V, this is the recommended amplitude to achieve the performance as stated.

5 Tested using the minimum VDRIVE voltage of 1.65 V with a 400 µA load current.

6 Tested using VDRIVE = 2.5 V with a 400 μA load current.
