NTE725 Dual Low Noise Preamp/OP Amp

Formerly: ECG725

Integrated Circuit Dual Low Noise Preamp/OP Amp

Description:

The NTE725 consists of two identical high-gain operational amplifiers cinstructed on a single chip. These 3-stage amplifiers use Class A PNP transistor output stages with uncommitted collectors. This enables a variety of loads to be employed for general purpose applications from DC to 10MHz, where two high end performance operation amplifiers are required. In addition, the outputs may be wired-OR for use as a dual comparator or they may function as diodes in low threshold rectifying circuits such as absolute value amplifiers, peak detectors, etc.

Features:

• Single or Dual Supply Operation
• Low Power Consumption
• High Gain
• Large Common Mode Range:  +11V, -13V
• Excellent Gain Stability vs. Supply Voltage
• No Latch-Up
• Output Short Circuit Protected

Absolute Maximum Ratings:

Supply Voltage		±18V
Internal Power Dissipation		650mW
Differential Input Voltage		±5V
Input Voltage (Note 1)		±15V
Output Short Circuit Duration (TA = +25°C, Note 2)		30sec
Operating Temperature Range		0° to +70°C
Storage Temperature Range		-55° to +125°C
Lead Temperature (During Soldering, 60sec)		+260°C

Note 1.	For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage.
Note 2.	Short circuit may be to GND or either supply.
