Key Features
- 4 fA typical input bias current enables accurate interfacing with ultra-high-impedance sources such as pH electrodes and piezoelectric sensors
- 36 µV maximum input offset voltage delivers precision DC accuracy without external trimming in 16-bit ADC front-ends
- 130 dB typical CMRR with 95 dB minimum ensures excellent common-mode interference rejection in differential measurement circuits
Applications
The LMP2012WGLQMLV is engineered for precision measurement front-ends in scientific instruments and medical diagnostic equipment where femtoampere-level input bias current is essential, such as ion-selective electrode pH meters and gas-sensor potentiostat circuits. Its 36 µV maximum offset voltage maintains DC accuracy in strain gauge and bridge amplifier circuits used in industrial weighing and pressure sensing. The dual-channel configuration in an SOIC-8 package also suits high-resolution data acquisition cards requiring matched input impedance on two independent signal channels.

Frequently Asked Questions
How does the 4 fA input bias current of LMP2012WGLQMLV benefit pH electrode amplifier designs?
pH electrodes present source impedances of 100 MΩ to 1 GΩ. With a bias current of only 4 fA, the resulting voltage error across a 1 GΩ electrode impedance is just 4 µV, which is negligible compared to the 59.2 mV per pH unit Nernst slope. In contrast, a standard JFET op-amp with 10 pA bias current would introduce 10 mV of error, equivalent to 0.17 pH measurement error.
In a strain gauge Wheatstone bridge amplifier, what does the 36 µV maximum offset voltage of LMP2012WGLQMLV mean for measurement resolution?
A 36 µV maximum offset voltage at the amplifier input, when amplified by a typical gain of 1000, appears as a 36 mV DC offset at the output. For a full-scale bridge output of 10 mV referenced to a 16-bit ADC, this offset represents 0.36% of span, which can be nulled digitally in firmware. The low offset ensures the residual uncorrected error after calibration remains below 10 LSB on a 16-bit measurement channel.
When evaluating LMP2012WGLQMLV for a space-qualified application, what qualification level does the QMLV suffix indicate?
The QMLV suffix designates that the LMP2012WGLQMLV is manufactured to MIL-PRF-38535 Class V (space level) qualification requirements. This means each lot undergoes 100% screening including burn-in at 125°C for 160 hours, hermetic seal testing, and radiation hardness assurance testing to a minimum total ionising dose tolerance suitable for low Earth orbit missions lasting 5 years to 15 years.
