The Maxim Integrated MAX549AEPA+ is a dual 8-bit voltage-output digital-to-analog converter using an R-2R ladder architecture. Each of the two DACs settles in 4µs typical, driven over an SPI bus.
The MAX549AEPA+ specifies integral and differential nonlinearity at ±0.9 LSB maximum. The 0.9 LSB bound is tight enough for 8-bit accuracy.
The ROHS3 compliance is current.
The output is voltage-unbuffered. The R-2R ladder provides a voltage output that should be buffered with an external op-amp for most loads, since the output impedance varies with the digital code.
It is supplied in an 8-pin PDIP (0.300-inch width, 7.62 mm body) for through-hole mounting. The shipping medium is Tube.
