Product details

JFET op-amp in a hermetic ceramic LCC — what this package tells you

The JFET input stage delivers 20 pA typical input bias current, which preserves signal accuracy when the source impedance is high, such as photodiode preamps or piezoelectric sensor buffers.

45 V/µs slew rate — large-signal bandwidth and settling

The 45 V/µs slew rate, combined with a 10 MHz gain-bandwidth product, means this op-amp can swing a 10 V peak-to-peak output at frequencies up to roughly 700 kHz without slew-rate limiting. That makes it suitable for fast-settling data-acquisition front ends, waveform generation, and audio line drivers where preserving transient integrity matters. The 48 mA output current per channel gives enough drive to handle a 600 Ω load or a modest capacitive load without external buffer stages.

Supply range and input offset — design margins

The supply span runs from 4.5 V to 38 V, so the part works on a single 5 V rail or split ±15 V supplies common in precision analog systems. Quiescent supply current is 1.6 mA per amplifier, which keeps the thermal budget manageable in the ceramic package.

Frequently asked questions

Can TLE2071AMFKB be used in audio applications?

Yes. The 45 V/µs slew rate and 10 MHz gain-bandwidth provide enough headroom for line-level audio up to the ultrasonic range. The JFET input keeps distortion low in high-impedance signal paths. However, the 470 µV input offset is higher than dedicated audio op-amps; if DC offset matters, plan for AC coupling or a servo loop.

What is the difference between TLE2071AMFKB and TLE2071MFKB?

The difference is in the ordering code suffix — 'A' versus no 'A'. Per TI's marking convention, the 'A' suffix typically indicates a tighter offset voltage grade or a specific test flow. The electrical characteristics (slew rate, GBW, supply range) are identical. If your BOM calls for the non-A version, the A version is a direct functional substitute.
