Measured with 2 V A IN range for AD9214-65. 3REFSENSE externally connected to AGND, REF is configured as an output for the internal reference voltage. 4REFSENSE externally connected to AV DD, REF is configured as an input for an external reference voltage. 510 k Ω to AV DD/3 on each input. 6I AVDD 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 A IN = full-scale dc input. Specifications subject to change without notice. (AVDD = 3 V, DrVDD = 3 V; TMIN = –40 C, TMAX = +85 C; external 1.25 V voltage reference and rated encode frequency used, unless otherwise noted.) |
