- 1ku List Price
- Starting From $1.13
Overview
- 8-Bit Resolution in a Miniature 6-Pin SOT23 Package
- Wide +2.7V to +5.5V Supply Range (MAX5385)
- < 1µA Shutdown Mode
- Software-Selectable Output Resistance During Shutdown
- Buffered Output Drives Resistive Loads
- Low-Glitch Power-On Reset to Zero DAC Output
- 3-Wire SPI/QSPI/MICROWIRE-Compatible Interface
- < ±5% Full-Scale Error (MAX5385)
- < ±1 LSB max INL/DNL
- Low 230µA (max) Supply Current
The MAX5383/MAX5384/MAX5385 low-cost, 8-bit digital-to-analog converters (DACs) in miniature 6-pin SOT23 packages have a simple 3-wire, SPI™/QSPI™/MICROWIRE™-compatible serial interface that operates up to 10MHz. The MAX5383 has an internal +2V reference and operates from a +2.7V to +3.6V supply. The MAX5384 has an internal +4V reference and operates from a +4.5V to +5.5V supply. The MAX5385 operates over the full +2.7V to +5.5V supply range and has an internal reference equal to 0.9 x VDD.
The MAX5383/MAX5384/MAX5385 require an extremely low supply current of only 150µA (typ) and provide a buffered voltage output. These devices power up at zero code and remain there until a new code is written to the DAC registers. This provides additional safety for applications that drive valves or other transducers that need to be off on power-up. The MAX5383/MAX5384/MAX5385 include a 1µA, low-power shutdown mode that features software-selectable output loads of 1kΩ, 100kΩ, or 1MΩ to ground.
