The MAX5138/MAX5139 are a family of single-channel pin-compatible and software-compatible 16-bit and 12bit DACs. The MAX5138/MAX5139 are low-power, 16bit/12-bit, buffered voltage-output, high-linearity DACs. They use a precision internal reference or a precision external reference for rail-to-rail operation. The MAX5138/MAX5139 accept a wide +2.7V to +5.25V supply-voltage range to accommodate most low-power and low-voltage applications. These devices accept a 3-wire SPITM-/QSPITM-/MICROWIRETM-/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 hard...
