MAX530

+5V, Low-Power, Parallel-Input, Voltage-Output, 12-Bit DAC

Single, Parallel, Voltage-Output DAC in a SSOP Package


Description

The MAX530 is a low-power, 12-bit, voltage-output digital-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 current 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) measures 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 possible without the use of external resistors or op amps. The parallel logic inputs are double buffered and are compatible 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.
