Product details

It delivers a gain bandwidth product of 1.7 MHz with a slew rate of 0.65 V/µs, drawing only 240 µA of supply current.

1.7 MHz GBW and 240 µA — the power-bandwidth trade-off

At 1.7 MHz gain bandwidth, this part is not a high-speed amplifier — it is sized for audio-band filtering, slow control loops, and DC-precise conditioning where the load step is measured in milliseconds, not nanoseconds. The 240 µA quiescent current is the headline advantage: compared to a general-purpose op amp that burns 1 mA or more, the TLE2021AIP keeps the power budget tight in loop-powered transmitters or battery-backed analog inputs. The 20 mA output drive per channel is enough to swing a 4-20 mA loop or drive a typical ADC reference buffer, but not a heavy cable or relay coil.

Supply range and input headroom

Rated for a 4 V to 40 V supply span, the TLE2021AIP accepts unregulated industrial rails without a pre-regulator. The 80 µV offset and 25 nA bias keep errors low.

Frequently asked questions

Is TLE2021AIP obsolete or end-of-life?

No. The TLE2021AIP is Active per the manufacturer lifecycle record. No EOL or last-time-buy notice applies.

What is a direct replacement for TLE2021AIP?

Texas Instruments has not published a direct replacement. For a surface-mount alternative with lower offset and rail-to-rail output, the TLV9351IDCKR (3.5 MHz, 20 V/µs slew rate, 10 pA bias) is a functional cross-shop candidate, but verify pinout, supply range, and package compatibility for your design.

Does TLE2021AIP have a pinout diagram?

The standard 8-pin PDIP pinout for a single op amp applies: offset null (pins 1 and 5), inverting input (pin 2), non-inverting input (pin 3), V- (pin 4), output (pin 6), V+ (pin 7), and NC (pin 8). The datasheet provides the full diagram.

What is the gain bandwidth product of TLE2021AIP?

The gain bandwidth product is 1.7 MHz.

Is TLE2021AIP pin compatible with LM741?

Yes, the TLE2021AIP uses the same 8-pin DIP pinout as the classic LM741: offset null, inverting input, non-inverting input, V-, output, V+, and offset null. However, the TLE2021AIP operates from a lower supply minimum (4 V vs. LM741's 10 V typical) and draws far less quiescent current.
