It re-l 1mV LSB WITH 4.095V FULL-SCALEquires a single +5V supply and contains an inputRANGEregister, latch, 2.435V reference, DAC, and high speedl COMPLETE WITH REFERENCErail-to-rail output amplifier. For a full-scale step, theoutput will settle to 1 LSB within 7m s. The devicel 12-BIT LINEARITY AND MONOTONICITYconsumes 2.5mW (0.5mA at 5V).OVER INDUSTRIAL TEMP RANGEThe parallel interface is compatible with a wide varietyl ASYNCHRONOUS RESET TO 0Vof microcontrollers. The DAC7621 accepts a 12-bitparallel word, has a double-buffered input logic struc-ture and provides data readback. In addition, twoAPPLICATIONScontrol pins provide a chip select (CS) function andl PROCESS CONTROLasynchronous clear (CLR) input.
