General Description

The MAX5500/MAX5501 integrate four low-power, 12-bit

digital-to analog converters (DACs) and four precision

output amplifiers in a small, 20-pin package. Each nega-

tive input of the four precision amplifiers is externally

accessible providing flexibility in gain configurations,

remote sensing, and high output drive capacity, making

the MAX5500/MAX5501 ideal for industrial-process-con-

trol applications. Other features include software shut-

down, hardware shutdown lockout, an active-low reset

which clears all registers and DACs to zero, a user-pro-

grammable logic output, and a serial-data output.

Each DAC provides a double-buffered input organized

as an input register followed by a DAC register. A 16-bit

serial word loads data into each input register. The seri-

al interface is compatible with SPI™/QSPI™/

MICROWIRE™. The serial interface allows the input and

DAC registers to be updated independently or simulta-

neously with a single software command. The 3-wire

interface simultaneously updates the DAC registers. All

logic inputs are TTL/CMOS-logic compatible. The

MAX5500 operates from a single +5V power supply,

and the MAX5501 operates from a single +3V power

supply. The MAX5500/MAX5501 are specified over the

extended -40°C to +105°C temperature range.
