The MAX5383EUT+T is a low power, 8bit digital to analogue converter (DAC) with 3-wire serial interface in 6 pin SOT-23 package. This device has an internal +2V reference, require an extremely low supply current of only 150μA (typ) and provide a buffered voltage output. It power-up at zero code and remain there until a new code is written to the DAC registers. It provides additional safety for applications that drive valves or other transducers that need to be off on power-up. This device is used in automatic tuning (VCO), power amplifier bias control, programmable threshold levels, automatic gain control and automatic offset adjustment.
Supply voltage range is 2.7V to 3.6V
Operating temperature range from -40°C to 85°C
Maximum supply current is 230μA at No load (VDD = +2.7V to +3.6V)
Maximum supply current is 1μA at shutdown mode (VDD = +2.7V to +3.6V)
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
Maximum INL/DNL is < ±1LSB, full-scale error is < ±10% at code =255, no load
