1 All static performance tests (except IOUT) are performed in a closed-loop system using an external precision OP177 I-to-V converter amplifier. The AD5544 RFB terminal is
tied to the amplifier output. Typical values represent average readings measured at 25 °C.
2 These parameters are guaranteed by design and not subject to production testing.
3 All input control signals are specified with tR = tF = 2.5 ns (10% to 90% of 3 V) and timed from a voltage level of 1.5 V.
4 All ac characteristic tests are performed in a closed-loop system using an OP42 I-to-V converter amplifier.
AD5554 ELECTRICAL CHARACTERISTICS
VDD = 5 V ±10%, VSS = 0 V, IOUTX = virtual GND, AGNDX = 0 V, VREFA, B, C, D = 10 V, TA = full operating temperature range, unless
otherwise noted.
