Applications
The LMV711IDCKRE4 is used in portable medical and consumer electronics for amplifying weak signals from photodiodes, pressure sensors, and capacitive touch interfaces where sub-picoamp leakage current is essential. Its tiny 6-pin SC-70 form factor and low bias current make it a preferred choice in wearable biometric devices and IoT sensor nodes operating from coin cells or small lithium batteries. The internal frequency compensation also simplifies active filter implementation in audio and data acquisition front ends requiring stable gain across varying load conditions.

Frequently Asked Questions
How does the 4 fA bias current of LMV711IDCKRE4 benefit photodiode transimpedance amplifier designs?
With a maximum input bias current of 4 fA (0.000004 µA), the LMV711IDCKRE4 introduces negligible offset current in transimpedance amplifier configurations using high-value feedback resistors of 1 MΩ or greater. This keeps the output DC error voltage in the sub-microvolt range, allowing accurate measurement of very low light levels from photodiodes in optical sensors and spectroscopy instruments.
What is the CMRR specification of LMV711IDCKRE4 and how does it affect differential signal rejection?
The LMV711IDCKRE4 specifies a minimum CMRR of 50 dB and a nominal CMRR of 75 dB. This means common-mode noise present equally on both inputs is attenuated by at least 316x (50 dB) before appearing at the output, keeping interference from power supply ripple or radiated noise from corrupting low-level sensor signals in single-supply 3.3V or 5V systems.
Is LMV711IDCKRE4 suitable for replacing a standard SOT-23 op-amp when board real estate must be minimized?
Yes. The LMV711IDCKRE4 uses a 6-pin SC-70 package, which has a footprint of approximately 2mm x 2.1mm — roughly 40% smaller than a standard SOT-23-5 footprint. Provided the replacement device meets the circuit's gain-bandwidth, offset voltage (3200 µV max), and supply voltage requirements, the SC-70 package allows a direct footprint swap with a smaller land pattern in wearable or densely packed PCB designs.
What supply voltage range does LMV711IDCKRE4 support for single-supply IoT sensor applications?
The LMV711IDCKRE4 is designed for low-voltage single-supply operation, typically supporting a supply range from 2.7V to 5V, making it compatible with 3V lithium coin cells, 3.3V LDO-regulated rails, and standard 5V USB-powered circuits. This wide range allows a single device variant to span multiple IoT platform power architectures without requiring separate device qualifications.
