• Manufacturer Part Number: max530bcwgt
• Description: Max530 +5v, Low-power, Parallel-input, Voltage-output, 12-bit Dac
• Manufacturer: Maxim Integrated Products, Inc.

The MAX530 is configured for a 0V to +2.048V unipolar
output range by connecting ROFS and RFB to VOUT
(Figure 9). The converter operates from either single or
dual supplies in this configuration. See Table 3 for the
DAC-latch contents (input) vs. the analog VOUT (output).
In this range, 1LSB = REFIN (2

A 0V to 4.096V unipolar output range is set up by con-
necting ROFS to AGND and RFB to VOUT (Figure 10).
Table 4 shows the DAC-latch contents vs. VOUT. The
MAX530 operates from either single or dual supplies in
this mode. In this range, 1LSB = (2)(REFIN)(2
