What are the key features of JL118BPA?
- ±20 V supply rating with 100 dB typical CMRR for high-precision differential and instrumentation amplifier configurations
- Low 0.25 µA max input bias current and 40 nA offset current enabling accurate high-impedance sensor interfaces
- 8-pin ceramic DIP (CDIP) package providing hermetic protection for mil/aero and high-reliability industrial environments
What is JL118BPA used for?
The JL118BPA is used in precision instrumentation and signal conditioning circuits where a wide ±20 V supply swing and high common-mode rejection of 100 dB are essential for accurate measurement. Its low 0.25 µA input bias current makes it well suited for interfacing with high-impedance transducers such as pH probes, photodiodes, and thermocouple amplifiers in scientific instruments. The ceramic DIP package qualifies the device for military, aerospace, and high-reliability industrial applications requiring long-term hermeticity.

Frequently Asked Questions
What supply voltage and CMRR does the JL118BPA offer for precision instrumentation designs?
The JL118BPA operates from a ±20 V dual supply and achieves a typical common-mode rejection ratio of 100 dB, with a minimum CMRR of 80 dB. This combination makes it suitable for differential measurement front-ends in industrial data acquisition and bridge amplifier circuits where noise rejection is critical.
How does the 0.25 µA input bias current of JL118BPA affect high-impedance sensor interfaces?
With a maximum input bias current of 0.25 µA and an offset current of only 40 nA, the JL118BPA introduces minimal error when connected to sensors with source impedances above 100 kΩ. This allows reliable signal conditioning of piezoelectric sensors, pH electrodes, and photodiode detectors without excessive voltage offset caused by bias current flowing through the source resistance.
When is JL118BPA in a ceramic DIP preferred over a plastic DIP op-amp for the same ±20 V application?
The ceramic DIP (CDIP-8) package provides hermetic sealing that plastic packages cannot match, making JL118BPA the correct choice for military, aerospace, and harsh industrial environments where moisture ingress or outgassing over decades of operation would degrade a plastic-encapsulated device. Ceramic packages also perform better in temperature cycling from -55°C to +125°C, a range often required by MIL-STD qualification.
Does JL118BPA require external frequency compensation, and how does that simplify circuit design?
No, JL118BPA does not require external frequency compensation because it is internally compensated, which eliminates the need for additional capacitors on the compensation pin. This simplifies PCB layout, reduces component count, and speeds up design validation, particularly in ±20 V gain stages where extra passive components on a high-impedance node could introduce noise or parasitic instability.
