General Description
The MAX5548 dual, 8-bit, digital-to-analog converter
(DAC) features high-output-current capability. The
MAX5548 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 MAX5548 typically consumes 1.5mA per DAC in
normal operation and less than 1A (max) in shutdown
mode. The MAX5548 also features low output leakage
current in shutdown mode (±1A 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 I2C-/SPI-compatible
serial interface provides optimum flexibility for the
MAX5548. The maximum programmable output current
value is set using software and an adjustment resistor.
The MAX5548 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.
