What are the key features of LM614IWM?
- Quad op-amp in a single package provides 4 independent amplifiers for multi-channel analog signal processing boards
- 90 dB typical common-mode rejection ratio reduces interference pickup in differential measurement applications
- 35 nA maximum input bias current at 25°C minimizes loading on moderate-impedance sensor and resistive divider sources
- Voltage-feedback architecture with internal frequency compensation enables stable operation with standard RC feedback networks
What is LM614IWM used for?
The LM614IWM is designed for general-purpose multi-channel analog signal conditioning, buffering, and amplification in industrial, consumer, and instrumentation circuits. Its quad configuration reduces component count and PCB area when four independent amplifier stages are needed in a single design. Typical uses include active filter banks, sensor pre-amplifiers, audio signal processing, and summing amplifiers in measurement instruments.

Frequently Asked Questions
How many op-amp channels does the LM614IWM contain, and what advantage does this offer in multi-channel PCB designs?
The LM614IWM integrates 4 independent op-amp channels into a single package. This reduces the PCB area and component count by approximately 75% compared to using four separate single op-amps, while also simplifying the bill of materials and lowering procurement overhead for multi-channel signal conditioning or active filter stages.
What is the CMRR of the LM614IWM, and how does it affect noise rejection in differential sensor circuits?
The LM614IWM achieves a typical CMRR of 90 dB with a minimum of 70 dB. In a differential sensor bridge interface, 90 dB CMRR means that a 1 V common-mode noise signal at the input appears as only 31 µV at the output, allowing accurate measurement of small differential signals in electrically noisy industrial environments.
What input bias current does the LM614IWM draw, and what source impedance range is suitable for its inputs?
The LM614IWM draws a maximum input bias current of 35 nA at 25°C. With this current level, source resistances up to approximately 100 kohm introduce less than 3.5 mV of bias-current-induced offset voltage, which is within the device's 7 mV maximum offset specification and acceptable for many general-purpose amplification stages.
Is the LM614IWM available in lead-free packaging, and does it comply with RoHS requirements?
The LM614IWM carries a Pbfree Code of No, indicating it is a tin-lead (SnPb) soldered package and does not conform to RoHS Directive requirements for lead-free assembly. Designers targeting RoHS-compliant products should source an alternative lead-free variant or a pin-compatible replacement such as the LM324 series in RoHS-compliant packaging.
