Frequently Asked Questions
What is the common-mode rejection ratio of the LM2904DE4 and why does it matter for sensor interfaces?
The LM2904DE4 offers a typical CMRR of 80 dB and a minimum of 50 dB, which is important for rejecting common-mode noise in sensor interfaces. This level of rejection ensures accurate signal amplification even in environments with electrical interference on both input lines.
How does having 2 op-amp channels in the LM2904DE4 benefit circuit board space and cost?
With 2 independent op-amp channels integrated into a single SOIC-8 package, the LM2904DE4 reduces component count and PCB area compared to using two separate single-channel amplifiers. This dual configuration also simplifies routing and can lower overall BOM cost in high-volume production.
What is the maximum input bias current of the LM2904DE4 and how does it affect high-impedance circuit design?
The LM2904DE4 has a maximum input bias current of 0.5 µA at room temperature, which introduces a small DC error voltage when used with high-value feedback resistors above 100 kΩ. Designers should account for this by using matched source impedances on both inputs to cancel the bias-current-induced offset.
