The TLE207x series of JFET-input operational amplifiers more than double the bandwidth and triple the slew rate of the TL07x and TL08x families of BiFET operational amplifiers. Texas Instruments Excalibur process yields a typical noise floor of 11.6 nV/Hz, 17-nV/Hz ensured maximum, offering immediate improvement in noise-sensitive circuits designed using the TL07x. The TLE207x also has wider supply voltage rails, increasing the dynamic signal range for BiFET circuits to ±19 V. On-chip zener trimming of offset voltage yields precision grades for greater accuracy in dc-coupled applications. The

Instructions for Using TLE2074CN
Power Supply:
- Ensure the supply voltage is within the range of 2.7V to 6.0V.
- Connect the positive supply (VCC) and ground (GND) pins correctly.
Input Signals:
- The input voltage should be within the range of 0V to VCC - 1.5V.
- Avoid exceeding the input voltage range to prevent damage to the device.
Output Configuration:
- The output voltage swing is from 0.03V to VCC - 0.03V.
- Ensure the load connected to the output does not exceed the maximum current rating of the op-amp.
Biasing and Compensation:
- Use appropriate biasing techniques to ensure the op-amp operates in its linear region.
- For high-frequency applications, consider adding compensation capacitors to maintain stability.
Temperature Considerations:
- The device is designed to operate over a wide temperature range, but performance parameters may vary with temperature.
- Refer to the datasheet for detailed temperature characteristics.
Layout and Grounding:
- Use proper PCB layout practices to minimize noise and parasitic effects.
- Ensure a solid ground plane and short, direct connections to the power supply and ground pins.
Storage and Handling:
- Store the device in a dry, static-free environment.
- Handle with care to avoid damaging the pins or the internal circuitry.
Testing and Troubleshooting:
- Before connecting the op-amp to your circuit, verify the power supply and signal levels.
- Use an oscilloscope to monitor the input and output signals for correct operation.
By following these guidelines, you can ensure optimal performance and reliability of the TLE2074CN operational amplifier in your application.
