NOTES: (1) For Two’s Complement Input Coding invert the MSB with an external logic inverter. (2) Digital inputs are TTL and +5V CMOS compatible over the specification

temperature range. (3) Open DATA input lines will be pulled above +5.5V. See discussion under LOGIC INPUT COMPATIBILITY in the OPERATION section. (4) FSR

means Full Scale Range. For example, for

±10V output, FSR = 20V. (5) Error at input code 800

HEX. (6) Maximum represents the 3σ limit. Not 100% tested for this

parameter. (7) For the worst-case code change: 7FFHEX to 800HEX and 800HEX to 7FFHEX. (8) Crosstalk is defined as the change in any output as a result of any other

output being driven from –10V to +10V at rated output current. (9) The maximum voltage at which ACOM and DCOM may be separated without affecting accuracy

specifications.
