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 mo-
tors, 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 (VEE).
Features:
DFull output swing at ±500mA
DHigh inductive load drive capability
DInternal flyback protection diodes
DLow power dissipation
DSingle or split supply operation
DCommon–mode range includes ground (VEE)
DHigh open loop gain
DLow input offset voltage
DLarge differential input voltage range
DThermal shutdown protection
DAvailable in Two Package Types:
NTE1854M: 8–Lead Mini DIP
NTE1854D: 14–Lead DIP
