To order >>> NTE987SM (14-SOIC)

Description:

The NTE987 and NTE987SM are low cost quad operational amplifiers with true differential inputs. These have several distinct advantages over standard operational amplifier types in single supply applications. The quad amplifier can operate at supply voltages as low as 3V or as high as 32V with quiescent currents about one fifth of those associated with the NTE941 (on a per amplifier basis). The common mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications. The output voltage range also includes the negative power supply voltage.

Features:

• Available in 14-Lead DIP (NTE987) and Surface Mount, SIOC-14 (NTE987SM)
• Short Circuit Protected Outputs
• True Differential Input Stage
• Single Supply Operation:   3V to 32V
• Four Amplifiers per Package
• Internally Compensated
• Common Mode Range Extends to Negative Supply
• Industry Standard Pin-Outs

Absolute Maximum Ratings:

Power Supply Voltage (Single Supply), VCC		32V
Power Supply Voltage (Split Supplies), VCC, VEE		±16V
Input Differential Voltage Range (Split Power Supplies), VIDR		±32V
Input Common Mode Voltage Range, VICR		-0.3V to 32V
Input Forward Current (VI < 0.3V, Note 1), IIF		50mA
Output Short Circuit Duration, tS		Continuous
Operating Junction Temperature, TJ		+150°C
Operating Ambient Temperature Range, TA		0° to +70°C
Storage Temperature Range, Tstg		-55°C to +125°C

Note 1.

This input current will only exist when the voltage is negative at any of the input leads. Normal output states will re-establish when the input voltage returns to a voltage greater than -0.3V.

Note 2.	The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is VCC-1.7V, but either or both inputs can go to +32V without damage.
Note 3.	Short circuits from the output to VCC can cause excessive heating and eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers.
