MAX5354CUA+T

Digital To Analog Converters Overview

The MAX5354CUA+T is a low-power, voltage-output, 10-bit digital-to-analog converter (DAC) integrated with a precision output amplifier in an 8-pin µMAX package. It operates from a single +5V supply and draws less than 280µA of supply current during normal operation. The device features a double-buffered input register structure compatible with SPI/QSPI and Microwire serial interfaces. Key electrical parameters include a typical settling time of 10µs to ±1/2LSB, a reference input range of 0V to VDD-1.4V, and a power-supply rejection ratio of 800µV/V. The unit supports software shutdown mode reducing current to 4µA and includes a power-on reset function.

• Remote industrial control units

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CUA' confirms the commercial temperature range of 0°C to +70°C and the 8-pin µMAX surface-mount package. Confirm RoHS compliance status as indicated by the '+' designation in the ordering information. Ensure the source documentation matches the Analog Devices or Maxim Integrated datasheet revision 19-1167 for accurate pinout and timing specifications.

Digital To Analog Converters Selection Notes

Select this component when a single +5V supply is available and low power consumption is required. The MAX5354 variant is appropriate for applications needing rail-to-rail output swing up to the supply voltage. Consider the external reference requirements, as the REF input impedance varies with the digital code. Verify that the serial interface timing meets the system clock constraints, specifically the 10MHz maximum SCLK frequency.

Digital To Analog Converters Part Context

The MAX5354CUA+T belongs to the MAX5354/MAX5355 family of 10-bit voltage-output DACs. It shares the same functional architecture and pinout as the MAX5355 but is optimized for +5V operation compared to the MAX5355's +3.3V design. Both devices utilize an inverted R-2R ladder network and are housed in identical 8-pin packages, facilitating direct interchangeability in designs where supply voltage differences are accommodated.
