The MAX5253BCAP+ is a +3V, quad, 12bit voltage-output DAC with serial interface in 20 pin SSOP package. The four voltage outputs, each amplifier's negative input are also available to the user. This facilitates specific gain configurations, remote sensing and high output drive capacity makes it ideal for industrial-process-control applications. It features software shutdown, hardware shutdown lockout, an active-low reset which 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 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. The DAC registers can be simultaneously updated through the 3-wire serial interface. All logic inputs are TTL/CMOS-logic compatible.
