The MAX5251BCAP+ from Maxim Integrated Products is a +3V, quad, 10bit voltage-output DAC with serial interface in 20 pin SSOP package. It combines four low-power, voltage output, 10bit DAC and four precision output amplifiers. In addition to the four voltage outputs, each amplifier"s negative input is also available to the user. This facilitates specific gain configurations, remote sensing and high output drive capacity. Other features include software shutdown, hardware shutdown lockout, an active-low reset that clears all registers and DACs to zero, a user-programmable logic output and a serial-data output. Each DAC has a double-buffered input organized as an input register followed by a DAC register. A 16bit serial word loads data into each input/DAC register. The 3-wire serial interface is compatible with SPI™/QSPI™ and MICROWIRE™. It allows the input and DAC registers to be updated independently or simultaneously with a single software command.
