Measured with 2 V AIN range for AD9214-65. 3REFSENSE externally connected to AGND, REF is configured as an output for the internal reference voltage. 4REFSENSE externally connected to AVDD, REF is configured as an input for an external reference voltage. 510 kΩ to AVDD/3 on each input. 6IAVDD is measured with an analog input of 10.3 MHz, 0.5 dBFS, sine wave, rated encode rate, and PWRDN = 0. See Typical Performance Characteristics and Applications section for IDrVDD. 7Power-down supply currents measured with PWRDN = 1; rated encode rate, A IN = full-scale dc input. 8Power consumption measured with AIN = full-scale dc input.
