MAX5135GTG+ Product Details
The MAX5135GTG+ from Maxim Integrated Products is a pin/software compatible, 12bit, voltage output DAC in 24 pin TQFN package. It is a low power, quad 12bit, buffered voltage-output, high-linearity DAC. This device accepts a wide +2.7V to +5.25V supply voltage range to accommodate most low power and low voltage applications. It also accept a 3-wire SPI/QSPI/MICROWIRE/DSP compatible serial interface to save board space and reduce the complexity of optically isolated and transformer isolated applications. The digital interface's double buffered hardware and software active-low LDAC provide simultaneous output updates. It include a hardware input to reset DAC outputs to zero or midscale upon power-up or reset providing additional safety for applications that drive valves or transducers that need to be off during power-up. The high linearity of the DACs makes this device ideal for precision control and instrumentation applications.
