MAX5500AGAP+

The MAX5500AGAP+ is a low power, quad, 12bit voltage output DAC with serial interface in 20 pin SSOP package. Each negative input of the four precision amplifiers is externally accessible providing flexibility in gain configurations, remote sensing and high output drive capacity, making the MAX5500 ideal for industrial-process-control applications. Other features include 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 provides a double-buffered input organized as an input register followed by a DAC register. A 16bit serial word loads data into each input register. The serial interface is compatible with SPI/QSPI/ MICROWIRE. The serial interface allows the input and DAC registers to be updated independently or simultaneously with a single software command. The 3-wire interface simultaneously updates the DAC registers.
