Product Overview
Archer catalog number 276-1715 packages an LF353N dual operational amplifier in an 8-pin DIP through-hole layout. Built with Motorola MC34002P silicon, this device pairs JFET input stages with bipolar output circuitry. It delivers fast slew rates, low input bias currents, and wide bandwidth for audio processing, active filter designs, and precision analog instrumentation.
Key Features
- Dual operational amplifier layout with 2 independent, internally compensated circuits
- Slew rate: 13 V/µs typical
- Input impedance: greater than 10^12 ohms typical
- Input offset voltage: 2.0 mVDC typical
- Supply voltage: single supply up to 36 VDC or dual supply up to ±18 VDC
- Output current: 40 mA source, 20 mA sink typical
- Built-in output short-circuit protection
- Standard 8-pin dual in-line package (DIP-8)
Applications
- Replacing degraded op amps during bench repairs of vintage audio preamplifiers, mixers, and equalizers.
- Breadboarding analog synthesizer modules, state-variable active filters, and high-impedance buffers.
- Servicing legacy test fixtures and analog sensor conditioning boards requiring DIP-8 JFET op amps.
Frequently Asked Questions
What is the pinout configuration for this IC?
The rear card diagram details the standard dual op amp 8-pin DIP pinout: pins 1 and 7 are outputs, pins 2 and 6 are inverting inputs, pins 3 and 5 are non-inverting inputs, pin 4 is negative supply or ground, and pin 8 is positive supply.
Is this an authentic Motorola component?
Yes. The IC sealed inside the Archer retail card is stamped with Motorola's stylized emblem alongside part numbers MC34002P and LF353N.
Why choose this individually packaged unit over bulk surplus?
This is an unused vintage unit preserved in its original packaging with legible factory markings, verified pinout documentation on the card, and straight leads protected from bench handling.
There is an honest charm to pegboard electronics from the golden age of tinkering, especially when Motorola silicon is waiting under the card. Pop it into an 8-pin socket and put those JFET inputs back to work.
