MAX5500AGAP+

P1-P3P4-P6P7-P9P10-P12P13-P15
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
