14-bit precision DAC with fast settling for industrial control loops
The Maxim MAX5544ESA+ is a 14-bit voltage-output digital-to-analog converter built around an R-2R ladder architecture. The unbuffered voltage output means the load impedance matters — plan for a downstream buffer if the DAC drives a low-impedance input or a long cable. Data transfer uses a standard SPI interface, which keeps the digital-side pin count low and lets the part talk to most microcontrollers without a glue-logic gate.
R-2R architecture and linearity — what the INL/DNL numbers mean
The integral nonlinearity is specified at ±4 LSB maximum, and the differential nonlinearity at ±0.5 LSB maximum. A DNL within ±0.5 LSB guarantees monotonicity.
Package and supply — layout constraints
The single 5 V supply rail for both analog and digital sections simplifies decoupling.
