MAX5309EUE+

The MAX5309EUE+ is a low power, low glitch, octal 10bit voltage output digital to analogue converter with serial interface in 16 pin TSSOP package. The wide supply voltage range and less than 215μA (max) supply current per DAC are excellent for low-power and low-voltage applications. The low 2nVs glitch energy of the MAX5309 makes them ideal for digital control of fast-response, closed-loop systems. The MAX5309 has a hardware reset input (CLR) which clears all registers and DACs to zero. The MAX5309 has a software shutdown feature that reduces the supply current to 1μA. The MAX5309 feature a load DAC (LDAC) function that updates the output of all eight DACs simultaneously. The 3-wire SPI, QSPI, MICROWIRE and DSP compatible serial interface allows the input and DAC registers to be updated independently or simultaneously with a single software command. This device uses a double-buffered design to minimize the digital noise feed-through from the digital inputs to the outputs.

• Supply voltage range is 2.7V to 5.5V
• Operating temperature range from -40°C to 85°C
• Fast settling time of 5μs
• Power-up reset to zero scale
