Operate from Single +5V Supply  
Buffered Voltage Output  
The MAX531/MAX538/MAX539 are low-power, voltage-  
output, 12-bit digital-to-analog converters (DACs) speci-  
fied for single +5V power-supply operation. The MAX531  
c a n a ls o b e op e ra te d with ± 5V s up p lie s . The  
MAX538/MAX539 draw only 140µA, and the MAX531  
(with inte rna l re fe re nc e ) d ra ws only 260µA. The  
MAX538/MAX539 come in 8-pin DIP and SO packages,  
while the MAX531 comes in 14-pin DIP and SO pack-  
ages. All parts have been trimmed for offset voltage,  
gain, and linearity, so no further adjustment is necessary.

140µA Supply Current (MAX538/MAX539)  
INL = ±1/2LSB (max)  
Guaranteed Monotonic over Temperature  
Flexible Output Ranges:  
The MAX538s buffer is fixed at a gain of +1 and the  
MAX539s buffer at a gain of +2. The MAX531s internal  
op amp may be configured for a gain of +1 or +2, as  
well as for unipolar or bipolar output voltages. The  
MAX531 can also be used as a four-quadrant multiplier  
without external resistors or op amps.
