MAX5741EUB+

The MAX5741EUB+ is a 10bit, quad, voltage-output digital to analogue converter (DAC) with serial interface in 10 pin µMAX package. Each DAC employs a resistor word string architecture that converts a 10bit digital input word to an equivalent analogue output voltage proportional to the applied reference voltage. It shares one reference input (REF) between all four DACs. It includes rail to rail output buffer amplifiers for each DAC and input logic for simple microprocessor (μP) and CMOS interfaces. The reference input accepts a voltage range from 0 to VDD. The 229μA supply current accommodates low power and low voltage applications. In power-down the reference input is high impedance, further reducing system’s total power consumption. It is used in automatic tuning, gain and offset adjustment, power amplifier control, process control I/O boards and VCO control.

• Supply voltage range is 2.7V to 5.5V
• Operating temperature range from -40°C to 85°C
• Power-down current is 0.3μA
• Safe power-up reset to zero volts at DAC output
• Three software-selectable power-down impedances (100Kohm, 1Kohm, Hi-Z)
• Fast 20MHz, 3-wire SPI, QSPI and MICROWIRE compatible serial interface
• Schmitt-triggered logic inputs for direct interfacing to optocouplers
• Maximum INL is ±4LSB, maximum DNL is ±1LSB & PSRR is 58.8dB
• Wake-up time is 8μs at VDD = +3V, DAC to DAC crosstalk of 2.4nV-s
• DAC to DAC crosstalk of 2.4nV-s
