MAX543BCSA+T

The MAX543BCSA+T is a CMOS, 12bit, serial input multiplying digital to analogue converter (DAC) in 8 pin NSOIC package. Its 3-wire serial interface saves additional board space and also results in low power dissipation. When used with microprocessors (µPs) with a serial port, the MAX543 minimizes the digital noise feedthrough from its input pins to its output. The serial port can be used as a dedicated analogue bus and kept inactive while the MAX543 is in use. Serial interfacing also reduces the complexity of opto or transformer isolated applications. The MAX543 contains a 12bit R-2R type DAC, a serial-in parallel out shift register, a DAC register and control logic. It is typically used at automatic calibration, motion control systems, µP-controlled systems, programmable amplifiers/attenuators and digitally controlled filters.
