Calibrated, Quad, 12-Bit Voltage-Output DACs with Serial Interface

The MAX536/MAX537 combine four 12-bit, voltage-output digital-to-analog converters (DACs) and four precision output amplifiers in a space-saving 16-pin package. Offset, gain, and linearity are factory calibrated to provide the MAX536's ±1 LSB total unadjusted error. The MAX537 operates with ±5V supplies, while the MAX536 uses -5V and +10.8V to +13.2V supplies.

Each DAC has a double-buffered input, organized as an input register followed by a DAC register. A 16-bit serial word is used to load data into each input/DAC register. The serial interface is compatible with either SPI/QSPI™ or MICROWIRE™, and allows the input and DAC registers to be updated independently or simultaneously with a single software command. The DAC registers can be simultaneously updated with a hardware active-low LDAC pin. All logic inputs are TTL/CMOS compatible.
