Quad Low Power Operational Amplifier – 14-Pin DIP

High Reliability Quad Op Amp for Precision Applications

The NTE987 is a quad low power operational amplifier IC featuring four independent, high-gain, internally frequency-compensated op amps in a single 14-pin Dual In-line Package (DIP). With its efficient design and robust performance, this device is ideal for signal conditioning, amplification, filtering, and general-purpose analog applications where both low power consumption and space-saving integration are required.

Key Features of the NTE987 Quad Op Amp

• Quad configuration: Four op amps in one standard 14-pin DIP
• Internally frequency compensated for unity gain stability
• Wide power supply range: Single or dual supplies from 3V to 32V
• Low power drain: Optimized for energy efficiency in portable and embedded systems
• Suitable for direct replacement for industry-standard LM324

Technical Specifications

• Input Offset Voltage: Typically 2mV
• Input Bias Current: Approximately 0.25µA at 5V
• Voltage Gain: Typically 100dB
• Common-Mode Rejection Ratio (CMRR): About 70dB
• Quiescent Current: Maximum 3mA
• Operating Temperature Range: 0°C to +70°C
• Package: 14-pin DIP (Dual In-line Package)
• Equivalent to NTE Part Number: NTE987

Typical Applications

• Signal amplification and conditioning
• Active filters and integrators
• Comparators and threshold detectors
• Audio pre-amplification and processing
• Analog control circuitry and sensor interfaces
