MAX536

MAX536/MAX537 19-0230; Rev 3; 3/11 Calibrated, Quad, 12-Bit Voltage-Output DACs with Serial Interface _______________General Description 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 LDAC pin. All logic inputs are TTL/CMOS compatible. ________________________Applications Industrial Process Controls Automatic Test Equipment Digital Offset and Gain Adjustment Motion Control Devices Remote Industrial Controls Microprocessor-Controlled Systems ________________Functional Diagram SDO LDAC DGND VDD AGND VSS TP REFAB DECODE CONTROL INPUT REG A DAC REG A 16-BIT SHIFT REGISTER INPUT REG B DAC REG B INPUT DAC REG C REG C SR CONTROL INPUT DAC REG D REG D MAX536/MAX537 DAC A OUTA DAC B OUTB DAC C OUTC DAC D OUTD CS SDI SCK REFCD _____...
