General Description
The MAX5550 dual, 10-bit, digital-to-analog converter
(DAC) features high-output-current capability. The
MAX5550 sources up to 30mA per DAC, making it ideal
for PIN diode biasing applications. Outputs can also be
paralleled for high-current applications (up to 60mA
typ). Operating from a single +2.7V to +5.25V supply,
the MAX5550 typically consumes 1.5mA per DAC in
normal operation and less than 1μA (max) in shutdown
mode. The MAX5550 also features low output leakage
current in shutdown mode (±1μA max) that is essential
to ensure that the external PIN diodes are off.
Additional features include an integrated +1.25V
bandgap reference, and a control amplifier to ensure
high accuracy and low-noise performance. A separate
reference input (REFIN) allows for the use of an external
reference source, such as the MAX6126, for improved
gain accuracy. A pin-selectable I
2
C*-/SPI-compatible
serial interface provides optimum flexibility for the
MAX5550. The maximum programmable output current
value is set using software and an adjustment resistor.
The MAX5550 is available in a (3mm x 3mm) 16-pin thin
QFN package, and is specified over the extended
(-40°C to +85°C) temperature range.
