q COMPLETE WITH REFERENCE AND OUTPUT AMPLIFIERS q 12-BIT PORT INTERFACE q ANALOG OUTPUT RANGE: �10V q MONOTONICITY GUARANTEED OVER TEMPERATURE q INTEGRAL LINEARITY ERROR: �1/2LSB max to �15V SUPPLIES q 28-PIN PLASTIC DIP PACKAGE

DESCRIPTION

is a complete quad 12-bit digital-to-analog converter with bus interface logic. Each package includes a precision +10V voltage reference, doublebuffered bus interface including a RESET function and 12-bit D/A converters with voltage-output operational amplifiers. The double-buffered interface consists a 12-bit input latch and a D/A latch for each D/A converter. A RESET control allows the D/A outputs to be asynchronously reset to bipolar zero, a feature useful for power-up reset, system initialization and recalibration. DAC4813 D/A converters are committed to the �10V output range only. Gain and offset are not externally adjustable.

DAC4813 is available with a integral linearity error of 1/2LSB and 12-bit monotonicity guaranteed over temperature. It is packaged 28-pin 0.6in. wide plastic DIP package and specified over to +85oC and to +70�C.

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 800HEX. (6) Maximum represents the 3 limit. Not 100% tested for this parameter. (7) For the worst-case code change: to 800HEX and 7FFHEX. (8) Crosstalk is defined as the change in any output as a result of any other output being driven from +10V at rated output current. (9) The maximum voltage at which ACOM and DCOM may be separated without affecting accuracy specifications.
