+5V, Low-Power, Parallel-Input,
Voltage-Output, 12-Bit DAC
_______________General Description
The MAX530 is a low-power, 12-bit, voltage-output digi-
tal-to-analog converter (DAC) that uses single +5V or
dual ±5V supplies. This device has an on-chip voltage
reference plus an output buffer amplifier. Operating cur-
rent is only 250µA from a single +5V supply, making it
ideal for portable and battery-powered applications. In
addition, the SSOP (Shrink-Small-Outline-Package) mea-
sures only 0.1 square inches, using less board area than
an 8-pin DIP. 12-bit resolution is achieved through laser
trimming of the DAC, op amp, and reference. No further
adjustments are necessary.
Internal gain-setting resistors can be used to define a
DAC output voltage range of 0V to +2.048V, 0V to
+4.096V, or ±2.048V. Four-quadrant multiplication is pos-
sible without the use of external resistors or op amps. The
parallel logic inputs are double buffered and are compati-
ble with 4-bit, 8-bit, and 16-bit microprocessors. For DACs
with similar features but with a serial data interface, refer
to the MAX531/MAX538/MAX539 data sheet.

Note 1: The output may be shorted to VDD, VSS, DGND, or AGND if the continuous package power dissipation and current ratings
are not exceeded. Typical short-circuit currents are 20mA.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
