MAX530 19-0168 Rev 3 7/95 +5V, Low-Power, Parallel-Input, Voltage-Output, 12-Bit DAC General Description Features Buffered Voltage Output The MAX530 is a low-power, 12-bit, voltage-output digi- tal-to-analog converter (DAC) that uses single +5V or Internal 2.048V Voltage Reference dual 5V supplies. This device has an on-chip voltage Operates from Single +5V or Dual 5V Supplies reference plus an output buffer amplifier. Operating cur- Low Power Consumption: rent is only 250A from a single +5V supply, making it 250A Operating Current ideal for portable and battery-powered applications. In 40A Shutdown-Mode Current addition, the SSOP (Shrink-Small-Outline-Package) mea- sures only 0.1 square inches, using less board area than SSOP Package Saves Space an 8-pin DIP. 12-bit resolution is achieved through laser 1 / Relative Accuracy: LSB Max Over 2 trimming of the DAC, op amp, and reference. No further Temperature adjustments are necessary. Guaranteed Monotonic Over Temperature Internal gain-setting resistors can be used to define a 4-Quadrant Multiplication with No External DAC output voltage range of 0V to +2.048V, 0V to Components +4.096V, or 2.048V. Four-quadrant multiplication is pos- Power-On Reset sible without the use of external resistors or op amps. The parallel logic inputs are double buffered and are compati- Double-Buffered Parallel Logic Inputs ble with 4-bit, 8-bit, and 16-bit microprocessors.

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.
