Product Introduction

Overview

The TLE2072AIDR is a high-performance BiFET operational amplifier from Texas Instruments, part of the TLE207x family. These amplifiers are known for their exceptional bandwidth, slew rate, and low noise characteristics, making them ideal for noise-sensitive and high-speed applications. The TLE2072AIDR offers significant improvements over earlier BiFET operational amplifiers such as the TL07x and TL08x, with more than double the bandwidth and triple the slew rate. This device is particularly suited for applications requiring high input impedance and good ac response, such as interfacing with high-impedance sensors or handling very low-level ac signals.

Key Features

  • Direct Upgrades to TL05x, TL07x, and TL08x BiFET Operational Amplifiers: The TLE2072AIDR is pin-compatible with lower performance BiFET operational amplifiers, making it easy to upgrade existing designs.
  • High Bandwidth and Slew Rate: More than double the bandwidth (10 MHz) and triple the slew rate (45 V/μs) compared to TL07x amplifiers.
  • Low Noise Floor: Ensured maximum noise floor of 17 nV/√Hz, with a typical noise floor of 11.6 nV/√Hz.
  • On-Chip Offset Voltage Trimming: Improves DC performance with precision grades for greater accuracy in dc-coupled applications.
  • Wider Supply Rails: Increases the dynamic signal range to ±19 V.
  • High Input Impedance: Inherently higher input impedance due to JFET-input transistors, suitable for high-impedance sensors or low-level ac signals.

Applications

  • Noise-Sensitive Circuits: Ideal for applications requiring low noise, such as audio equipment, medical devices, and precision measurement instruments.
  • High-Speed Applications: Suitable for high-speed data acquisition, video processing, and other applications needing fast response times.
  • High-Impedance Sensors: Excellent for interfacing with high-impedance sensors due to its high input impedance.
  • Low-Level AC Signals: Handles very low-level ac signals effectively, making it suitable for applications like tone control in audio systems.

Q & A

    The bandwidth of the TLE2072AIDR is 10 MHz.

  2. How does the slew rate of the TLE2072AIDR compare to the TL07x?

    The TLE2072AIDR has a slew rate that is three times higher than the TL07x, at 45 V/μs.

  3. What is the typical noise floor of the TLE2072AIDR?

    The typical noise floor of the TLE2072AIDR is 11.6 nV/√Hz, with an ensured maximum of 17 nV/√Hz.

  4. What is the supply voltage range for the TLE2072AIDR?

    The supply voltage range for the TLE2072AIDR is ±2.25 V to ±19 V.

  5. Is the TLE2072AIDR pin-compatible with other BiFET operational amplifiers?

    Yes, the TLE2072AIDR is pin-compatible with lower performance BiFET operational amplifiers like the TL05x, TL07x, and TL08x.

  6. What is the operating temperature range for the TLE2072AIDR?

    The operating temperature range for the TLE2072AIDR is −40°C to 85°C.

  7. What are the key applications for the TLE2072AIDR?

    The TLE2072AIDR is suitable for noise-sensitive circuits, high-speed applications, high-impedance sensors, and low-level ac signals.

  8. How does the input impedance of the TLE2072AIDR compare to bipolar or CMOS devices?

    The TLE2072AIDR has inherently higher input impedance due to its JFET-input transistors, without sacrificing the output drive associated with bipolar amplifiers.

  9. What is the common mode rejection ratio (CMRR) of the TLE2072AIDR?

    The CMRR of the TLE2072AIDR ranges from 70 dB to 89 dB.

  10. How does the TLE2072AIDR handle single-supply operations?

    When operating from a single supply, care must be taken to observe common-mode input voltage limits and output swing. DC biasing of the input signal is required, and loads should be terminated to a virtual ground node at mid-supply.
