The MAAL-008624 also features flexible biasing to
control the current consumption vs. dynamic range
trade-off. The MAAL-008624 can operate from any
supply voltage in the 3 V to 8 V range. Its current
can be controlled over a range of 20 mA to 80 mA
with an external resistor.

The MAAL-008624 is ideally suited for use where
low noise figure, high gain, high dynamic range,
and low power consumption are required. Typical
applications include receiver front ends in
CDMA450 base stations. It is also useful as a gain
block, buffer, driver, and IF amplifier in both fixed
and portable cellular and 450 MHz ISM
systems.
