MAX503

19-0279; Rev 0; 8/94 5V, Low-Power, Parallel-Input, Voltage-Output, 10-Bit DAC _______________General Description The MAX503 is a low-power, 10-bit, voltage-output digitalto-analog converter (DAC) that uses single 5V or dual ±5V supplies. This device has an internal voltage reference plus an output buffer amplifier. Operating current is only 250µA from a single 5V supply, making it ideal for portable and battery-powered applications. In addition, the shrink smalloutline package (SSOP) measures only 0.1 square inches, using less board area than an 8-pin DIP. 10-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 possible without the use of external resistors or op amps. The parallel logic inputs are double buffered and are compatible with 4-bit, 8bit, and 16-bit microprocessors. For a hardware and software compatible 12-bit upgrade, refer to the MAX530 data sheet. For DACs with similar features but with a serial data interface, refer to the MAX504/MAX515 data sheet. ____________________________Features o o o o o o o o o o Buffered Voltage Output Internal 2.048V Voltage Reference Operates from Single 5V or Dual ±5V Supplies Low Power Consumption: 250µA Operating Current 40µA Shutdown-Mode Current SSOP Package Saves Space Relative Accuracy: ±1/2 LSB Ma...
