Dual 8-bit DAC in a through-hole DIP — what it is and where it fits
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.
INL/DNL and monotonicity — what the ±0.9 LSB max means for your loop
The MAX549AEPA+ specifies integral and differential nonlinearity at ±0.9 LSB maximum. The 0.9 LSB bound is tight enough for 8-bit accuracy.
Active lifecycle — no LTB pressure on this BOM line
The MAX549AEPA+ carries an Active product status per the manufacturer. The ROHS3 compliance is current. For a BOM line that needs a through-hole dual DAC, this part does not carry an end-of-life clock.
