Dual Power Operational
Amplifier
Description
The NCx5652 is a dual power operational amplifier with a versatile
output stage configuration that allows conventional op−amp biasing or
user tuning of efficiency, isolation, or current monitoring. Integrated
flyback diodes protect the amplifiers during inductive load transients.
Operating at supply voltages as low as 3.3 V, the NCx5652 is capable
of delivering 500 mA of current while maintaining an excellent output
swing. The integrated thermal shutdown circuit protects the NCx5652
from excessive power dissipation. A thermal warning flag is provided
for external monitoring of the device, providing a flexible interface to
a system’s microcontroller. This open−collector thermal flag output
doubles as a DISABLE input that can be used to tri−state both
amplifier outputs under user control. The 12−pin UDFN 3x3 mm
package provides thermal robustness while achieving space savings
on high density PCBs.
