♦ Buffered Voltage Output
♦ Internal 2.048V Voltage Reference
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.
♦ 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 Max Over

Temperature
♦ Guaranteed Monotonic Over Temperature
Internal gain-setting resistors can be used to define a
DAC outp ut volta g e ra ng e 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.

Components
♦ Power-On Reset
