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
output amplifiers in a space-saving 16-pin package.
Offset, gain, and linearity are factory calibrated to provide
the MAX536’s 1 ꢀLS total unadꢁusted error. The
MAX537 operates with 5ꢂ supplies, while the MAX536
uses -5ꢂ and +10.8ꢂ to +13.2ꢂ supplies.
♦ Simultaneous or Independent Control of Four
DACs via a 3-Wire Serial Interface
♦ Power-On Reset
♦ SPI/QSPI and MICROWIRE Compatible

♦ Full 12-Bit Performance without Adꢃustments
X5 Supplꢇ Operation ꢄMAꢅX3ꢈ6
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
LPI/QLPI™ 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 TTꢀ/CMOL compatible.
