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.
