MAX503 19-0279 Rev 0 8/94 5V, Low-Power, Parallel-Input, Voltage-Output, 10-Bit DAC General Description Features Buffered Voltage Output The MAX503 is a low-power, 10-bit, voltage-output digital- to-analog converter (DAC) that uses single 5V or dual 5V Internal 2.048V Voltage Reference supplies. This device has an internal voltage reference plus Operates from Single 5V or Dual 5V Supplies an output buffer amplifier. Operating current is only 250A Low Power Consumption: from a single 5V supply, making it ideal for portable and 250A Operating Current battery-powered applications. In addition, the shrink small- 40A Shutdown-Mode Current outline package (SSOP) measures only 0.1 square inches, using less board area than an 8-pin DIP. 10-bit resolution is SSOP Package Saves Space achieved through laser trimming of the DAC, op amp, and 1 / Relative Accuracy: LSB Max Over 2 reference. No further adjustments are necessary. Temperature Internal gain-setting resistors can be used to define a DAC Guaranteed Monotonic Over Temperature output voltage range of 0V to +2.048V, 0V to +4.096V, or 4-Quadrant Multiplication with No External 2.048V. Four-quadrant multiplication is possible without Components the use of external resistors or op amps. The parallel logic Power-On Reset inputs are double buffered and are compatible with 4-bit, 8- bit, and 16-bit microprocessors. For a hardware and soft- Double-Buffered Parallel Logic Inputs ware compatible 12-bit upgrade, refer to the MAX530 data sheet. For DACs with similar features but with a serial data Ordering Information interface, refer to the MAX504/MAX515 data sheet. PART TEMP.

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.
