Eight-channel DAC in a compact QSOP footprint
The MAX5259EEE+ from Analog Devices packs eight 8-bit voltage-output DACs into a 16-pin QSOP package (3.90 mm width) — a density that saves board area when multiple analog outputs are needed for trim, bias, or set-point control. Each DAC uses a string architecture with buffered voltage output, settling to within 1 LSB in 7 µs typical — fast enough for multiplexed updates across all eight channels in under 60 µs. The SPI data interface keeps pin count low; a single 3-wire bus controls all eight converters, which is useful when the host MCU has limited I/O.
Industrial temperature and supply rail flexibility
An external reference sets the output span; the user selects the reference voltage that matches the ADC or sensor full-scale, giving flexibility across different system voltage domains. INL and DNL are each ±0.1 LSB — this is better than the typical ±0.5 LSB for many 8-bit DACs, meaning monotonicity is guaranteed and the output code-to-voltage mapping stays accurate across temperature.
