Product details

JFET input stage for high-impedance signal chains

The Texas Instruments OPA141AIDR is a single-channel JFET-input operational amplifier in an 8-SOIC package. Its 2 pA input bias current and 10 MHz gain-bandwidth product make it a fit for precision analog front-ends — photodiode transimpedance amplifiers, pH probe buffers, or charge amplifiers where the JFET input keeps leakage from corrupting the measurement. The rail-to-rail output swings to within millivolts of each supply rail, useful when driving a single-supply ADC input without an extra level-shift stage.

Operates from a single 4.5 V supply up to 36 V, or dual supplies. Quiescent current is 1.8 mA.

Frequently asked questions

Is OPA141AIDR rail-to-rail output?

Yes, the output type is rail-to-rail, allowing the output to swing close to both supply rails.

What is OPA141AIDR equivalent?

A functional alternative is the TLV9351IDCKR, a general-purpose op-amp with 20 V/µs slew rate and 10 pA input bias, but its 3.5 MHz GBW is lower than the OPA141's 10 MHz. The OPA141's JFET input stage is the key differentiator for high-impedance applications.
