Unipolar Configuration

Figure 2a shows the MAX5441–MAX5444 configured for

unipolar operation with an external op amp. The op amp

is set for unity gain, and Table 1 lists the codes for this

circuit. The bipolar MAX5442/MAX5444 can also be

used in unipolar configuration by connecting RFB and

INV to REF. This allows the DAC to power-up to mid-

scale.

Bipolar Configuration

Figure 2b shows the MAX5442/MAX5444 configured for

bipolar operation with an external op amp. The op amp

lists the offset binary codes for this circuit.

Power-Supply Bypassing and

Ground Management

leads close to the device (less than 0.25 inches).
