(1) Specifications subject to change without notice.
(2) All static performance tests (except I_OUT) are performed in a closed-loop system using an external precision OPA277 I-to-V converter
amplifier. The DAC8803 R_FB terminal is tied to the amplifier output. Typical values represent average readings measured at 25°C.
(3) These parameters are specified by design and not subject to production testing.
(4) All input control signals are specified with t_R = t_F = 2.5 ns (10% to 90% of 3 V) and timed from a voltage level of 1.5 V.
