MAX5150, MAX5151 低功耗、双路、13位、电压

max5150, max5151 低功耗、双路、13位、电压输出dac,串行接口 the max5150/max5151 low-power, serial, voltage-output, dual 13-bit digital-to-analog converters (dacs) consume only 500µa from a single +5v (max5150) or +3v (max5151) supply. these devices feature rail-to-rail output swing and are available in a space-saving 16-pin qsop package. to maximize the dynamic range, the dac output amplifiers are configured with an internal gain of +2.
the 3-wire serial interface is spi™/qspi™ and microwire™ compatible. each dac has a double-buffered input organized as an input register followed by a dac register, which allows the input and dac registers to be updated independently or simultaneously with a 16-bit serial word. additional features include programmable shutdown (2µa), hardware-shutdown lockout, a separate reference voltage input for each dac that accepts ac and dc signals, and an active-low clear input (cl) that resets all registers and dacs to zero. these devices provide a programmable logic pin for added functionality, and a serial-data output pin for daisy-chaining.
