MAX536/MAX537 19-0230 Rev 3 3/11 Calibrated, Quad, 12-Bit Voltage-Output DACs with Serial Interface General Description Features Four 12-Bit DACs with Output Buffers The MAX536/MAX537 combine four 12-bit, voltage-output digital-to-analog converters (DACs) and four precision Simultaneous or Independent Control of Four output amplifiers in a space-saving 16-pin package. DACs via a 3-Wire Serial Interface Offset, gain, and linearity are factory calibrated to provide Power-On Reset the MAX536s 1 LSB total unadjusted error. The SPI/QSPI and MICROWIRE Compatible MAX537 operates with 5V supplies, while the MAX536 1 LSB Total Unadjusted Error (MAX536) uses -5V and +10.8V to +13.2V supplies. Full 12-Bit Performance without Adjustments Each DAC has a double-buffered input, organized as 5V Supply Operation (MAX537) an input register followed by a DAC register. A 16-bit Double-Buffered Digital Inputs serial word is used to load data into each input/DAC register. The serial interface is compatible with either Buffered Voltage Output SPI/QSPI or MICROWIRE, and allows the input and 16-Pin DIP/SO Packages DAC registers to be updated independently or simulta- Ordering Information neously with a single software command. The DAC reg- isters can be simultaneously updated with a hardware PIN- INL LDAC pin. All logic inputs are TTL/CMOS compatible.
