12-bit dual DAC with SPI interface
The MAX5104CEE+ is a 12-bit dual voltage-output digital-to-analog converter from Maxim Integrated, packaged in a 16-QSOP surface-mount package. It integrates two DACs on one die, each with a buffered voltage output, and communicates over an SPI-compatible serial interface. The R-2R resistor-ladder architecture ensures inherent monotonicity, and the device operates from a single 5V supply for both analog and digital rails.
Settling time and throughput
Typical settling time to ±0.5 LSB is 15 µs, which sets the maximum update rate at roughly 66 kHz per channel when the SPI clock is fast enough to load the data within the settling window. For applications requiring simultaneous updates across both channels, the dual DAC architecture allows independent data loading and conversion, though the settling time applies per channel.
Accuracy and linearity
Integral nonlinearity is specified at ±4 LSB maximum, and differential nonlinearity at ±1 LSB maximum. The ±1 LSB DNL guarantee ensures no missing codes across the full 12-bit range, which is critical for closed-loop control and waveform generation. The external reference input sets the full-scale output voltage; the reference voltage directly scales the output span, so the reference noise and drift appear at the output multiplied by the DAC gain.
Temperature grade and supply rail
Both the analog and digital supply pins require 5V ±10% — no separate digital rail is needed, simplifying the power tree. The device does not include an internal reference; an external precision reference must be supplied.
Package and board integration
Housed in a 16-lead QSOP (0.154-inch body width, 3.90 mm), the package footprint is compatible with standard 16-SSOP land patterns. The device is supplied in tube packaging, suitable for hand assembly or low-volume pick-and-place. Surface-mount mounting is required per the datasheet.
It is RoHS3 compliant (2011/65/EU + 2015/863). No official successor or direct pin-compatible replacement is recorded — the part remains the current production offering for this dual 12-bit DAC function.
