NTE1854D/NTE1854M
Integrated Circuit
Dual Power Operational Amplifier
Description:
The NTE1854D/NTE1854M is a monolithic dual–power operational amplifier which features a high
current, low saturation voltage, flyback protected output stage optimized for driving heavy inductive
loads. Capable of operation in a single supply mode form as low as 4.5V up to 13.2V, the
NTE1854D/NTE1854M is ideally suited for the computer peripheral environment, driving small motors, solenoids, and linear actuators in an H–bridge configuration.
As a general–purpose op amp, the NTE1854D/NTE1854M exhibits low input offset voltage, high open
loop gain, low quiescent current, a large differential input voltage range, and a common–mode input
voltage range which includes ground (V
