MAXIM INTEGRATED PRODUCTS  MAX5590BEUG+  数模转换器, 缓冲, 快速设置, 电压输出, 12 bit, 串行, 2.7V 至 5.25V, TSSOP, 24 引脚

The is a buffered, fast-settling, octal, 12bit, voltage-output digital to analogue converter DAC in 24 pin TSSOP package. It operate from a +2.7V to +5.25V analogue supply and a separate +1.8V to +5.25V digital supply. The 20MHz 3-wire serial interface is compatible with SPI, QSPI, MICROWIRE and digital signal processor DSP protocol applications. It share a common serial interface in direct-access or daisy-chained configuration. It provides two multifunction, user-programmable, digital I/O ports. The externally selectable power-up states of the DAC outputs are either zero scale, midscale or full scale. Software-selectable FAST and SLOW settling modes decrease settling time in FAST mode or reduce supply current in SLOW mode. It is used in automatic test equipment ATE, digital offset and gain adjustment, automatic tuning, programmable attenuators and power amplifier control.
