数模转换器, 8 bit, SPI, 1.8V 至 5.5V, µMAX, 8 引脚

The from Products is a dual, ultralow power, 8bit, voltage output DAC in 8 pin µMAX package. This DAC offering rail to rail buffered voltage outputs and consume less than 5µA making the device suitable for low power and low voltage applications. A shutdown mode reduces overall current, including the reference input current to just 0.18µA. Upon power-up, outputs are driven to zero scale, providing additional safety for applications that drive valves or for other transducers that need to be off during power-up. The zero-scale outputs enable glitch-free power-up. Device is suitable for low power and low voltage applications and also used in automatic trimming and calibration in factory or field, portable battery powered devices instrumentation, programmable voltage and current sources, chemical sensor cell bias for gas monitors, programmable LCD bias, industrial process control and remote industrial devices, remote data conversion and monitoring.
