(1) Shaded cells indicate same specification as the DAC712P, U grade.
(2) Digital inputs are TTL- and +5V CMOS-compatible over the specified temperature range.
(3) Errors externally adjustable to zero.
(4) FSR means Full-Scale Range. For example, for a ± 10V output, FSR = 20V.
(5) Maximum represents the 3 σ limit. Not 100% tested for this parameter.
(6) For the worst-case code changes: FFFFh to 0000h and 0000h to FFFFh. These are binary twos complement (BTC) codes.
