Frequently Asked Questions
What is the input bias current of the LF353M?
The LF353M features an extremely low maximum input bias current (IIB) of 0.2 pA (0.0002 µA) at 25°C, thanks to its JFET input stage. This makes it ideal for high-impedance sensor interfaces and precision integrator circuits where leakage currents must be minimized.
What are the typical applications of the LF353M?
The LF353M is commonly used in audio preamplifiers, active filters, instrumentation amplifiers, sample-and-hold circuits, and industrial sensor interfaces. Its dual-channel design and low input bias current make it well suited for differential signal processing and precision analog front-end designs.
What package does the LF353M come in, and are there pin-compatible alternatives?
The LF353M is available in an 8-pin SOIC (Small Outline Integrated Circuit) package, also designated MS-012AA. Pin-compatible alternatives include the TL072 and RC4558 dual op-amps in SOIC-8; however, those devices use bipolar inputs with higher bias currents compared to the JFET-input LF353M.
What is the common-mode rejection ratio (CMRR) of the LF353M?
The LF353M achieves a minimum CMRR of 70 dB and a typical CMRR of 100 dB. This high rejection ratio ensures that common-mode noise signals, such as power-supply hum or electromagnetic interference picked up on both input lines, are effectively suppressed at the output.
