12-Bit, Voltage Output DIGITAL-TO-ANALOG CONVERTER
FEATURES
q LOW POWER: 1.8mW q UNIPOLAR OR BIPOLAR OPERATION q SETTLING TIME: 10µs to 0.012% q 12-BIT LINEARITY AND MONOTONICITY: 40°C to +85°C q DATA READBACK q DOUBLE-BUFFERED DATA INPUTS q 24-LEAD SSOP PACKAGE
DESCRIPTION
The DAC7613 is a 12-bit, voltage output digital-toanalog converter with guaranteed 12-bit monotonic performance over the specified temperature range. The DAC7613 accepts a 12-bit parallel input data, has double-buffered DAC input logic and provides a readback mode of the internal input register. An asynchronous reset clears all registers to a mid-scale code of 800H or to a zero-scale of 000H. The DAC7613 can operate from a single +5V supply or from +5V and 5V supplies. Low power and small size makes the DAC7613 ideal for data acquisition systems and closed-loop servocontrol. The DAC7613 is available in a plastic SSOP-24 package, and offers guaranteed specifications over the 40°C to +85°C temperature range.

NOTES: (1) If VSS = 0V, specification applies at code 00AH and above. (2) LSB means Least Significant Bit, when V REFH equals +2.5V and VREFL equals 2.5V, then one LSB equals 1.22mV. (3) Ideal output voltage, does not take into account zero or full-scale error. (4) If VSS = 5V, full-scale 5V step. If VSS = 0V, full-scale positive 2.5V step and negative step from code FFFH to 00AH.

Exposure to absolute maximum conditions for extended periods may affect device reliability.
ELECTROSTATIC DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Sets minimum output voltage for the DAC. Not Internally Connected Reference Input Voltage High. Sets maximum output voltage for the DAC. Negative Analog Supply Voltage, 0V or 5V nominal. Ground Positive Power Supply DAC Voltage Output The selected DAC register becomes transparent when LOADDAC is LOW. It is in the latched state when LOADDAC is HIGH. Asynchronous Reset Input. Sets the DAC register to either zero-scale (000H) or mid-scale (800H) when LOW. RESETSEL determines which code is active. When LOW, a LOW on RESET will cause the DAC register to be set to code 000H. When RESETSEL is HIGH, a LOW on RESET will set the registers to code 800H. Chip Select. Active LOW. Enabled by CS. Controls data read and write from the input register.
