MAX536_11 Datasheet, PDF (1/24 Pages) Maxim Integrated Products – Calibrated, Quad, 12-Bit Voltage-Output DACs with Serial Interface

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 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.
