产品概述

The MAX5805BAUB+ is an ultra small, single channel, 12bit buffered output voltage DAC with internal reference and I2C interface in 10 pin µMAX package. An internal reference has a software selectable option of 2.048V, 2.5V or 4.096V. A precision external reference input allows rail to rail operation and presents a 100Kohm load to an external reference. It has an I2C compatible, 2-wire interface that operates at clock rates up to 450KHz. The DAC output is buffered and has a low supply current of 155µA (typical at 3.5V) and a low offset error of ±0.5mV. On power-up, the MAX5805 reset the DAC outputs to zero, providing additional safety for applications that drive valves or other transducers which need to be off on power-up. It includes a user configurable active-low asynchronous input for additional flexibility. This input can be programmed to asynchronously clear or temporarily gate DAC output to a user-programmable value. The active-low asynchronous LDAC input is also included.
  • Supply voltage range is 2.7V to 5.5V
  • Operating temperature range from -40°C to 125°C
  • ±1LSB INL buffered voltage output
  • Low power consumption of less than 1mW
  • Three software selectable power-down output impedances of 1Kohm, 100Kohm or high impedance
  • Settling time is 6.3µs
  • Output directly drives 2Kohm loads
  • Internal reference tempco is 10ppm/°C (typ), 25ppm/°C (max)
