Product details

Dual JFET op-amp for high-impedance signal conditioning

Two independent channels share a common supply, which can range from 7 V to 36 V — covering ±15 V bipolar rails or a single 12 V or 24 V industrial supply without a secondary regulator.

The LF353DR operates from a 7 V minimum to a 36 V maximum supply span, which covers common analog rails: ±5 V (10 V total), ±12 V (24 V total), and ±15 V (30 V total) as well as single 12 V or 24 V supplies. For industrial or automotive temperature ranges, a different JFET op-amp with an extended temperature rating would be needed.

Frequently asked questions

Is LF353DR a JFET op amp?

Yes, the LF353DR is a dual JFET-input operational amplifier. The JFET input stage gives it a 50 pA input bias current, which is orders of magnitude lower than a standard bipolar-input op-amp, making it suitable for high-impedance sensor interfaces.

What is the equivalent of LF353DR?

A close functional peer is the TLV9362IDDFR, a dual general-purpose op-amp with a 10.6 MHz GBWP, 25 V/µs slew rate, 10 pA input bias, and rail-to-rail output. The TLV9362IDDFR offers higher bandwidth and rail-to-rail output but uses a different input topology; verify pin compatibility and supply range for your specific board layout.
