MAX5354EUA+

The MAX5354EUA+ is a 10bit voltage-output digital to analogue converter (DAC) in 8 pin µMAX package. This DAC easily addressed using a simple 3-wire serial interface & includes a 16bit shift register and has a double buffered input composed of an input register and a DAC register. The DAC is an inverted R-2R ladder network that converts a digital input (10 data bits plus three sub-bits) into an equivalent analogue output voltage in proportion to the applied reference voltage. The output amplifier’s inverting input is available to the user allowing specific gain configurations, remote sensing and high output current capability. A 16bit serial word loads data into the input register. The DAC register can be updated independently or simultaneously with the input register. All logic inputs are TTL/CMOS logic compatible and buffered with Schmitt triggers to allow direct interfacing to optocouplers. This is used in digital offset and gain adjustment and microprocessor-controlled systems.

• Supply voltage range is 4.5V to 5.5V
