♦ Four 12-Bit DACs with Output Buffers
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 ±1LSB total unadjusted error. The MAX537
operates with ±5V supplies, while the MAX536 uses -5V
and +12V to +15V supplies.
♦ Simultaneous or Independent Control of Four
DACs via a 3-Wire Serial Interface
♦ Power-On Reset
♦ SPI/QSPI and Microwire Compatible
♦ ±1LSB Total Unadjusted Error (MAX536)
♦ Full 12-Bit Performance without Adjustments
♦ ±5V Supply Operation (MAX537)
♦ Double-Buffered Digital Inputs
♦ Buffered Voltage Output
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 simulta-
neously with a single software command. The DAC reg-
isters can be simultaneously updated with a hardware
LDAC pin. All logic inputs are TTL/CMOS compatible.
