Texas Instruments TLE2071 Low-Noise High-Speed JFET-Input Operational Amplifier TLE2071IDG4

The TLE2071IDG4 is a low-noise, high-speed JFET-input operational amplifier from Texas Instruments, designed to provide superior performance in noise-sensitive applications. It features a typical noise floor of 11.6 nV/,àöHz and an ensured maximum noise specification of 17 nV/,àöHz, making it suitable for high-precision circuits. The amplifier offers more than double the bandwidth (10 MHz) and triple the slew rate (45 V/Oºs) compared to the TL07x series, enhancing its capability in dynamic signal processing. The TLE2071 operates with wider supply voltage rails, allowing for a dynamic signal range of ¬±19 V, which is beneficial for various applications. It includes on-chip offset voltage trimming to improve DC performance, ensuring greater accuracy in DC-coupled systems. The device is pin-compatible with lower-performance BiFET operational amplifiers, facilitating upgrades in existing designs without significant redesign efforts. This operational amplifier is fully specified for operation at ¬±15 V and ¬±5 V, and it is particularly well-suited for interfacing with high-impedance sensors and low-level AC signals due to its high input impedance. Care should be taken when using it with single power supplies, as DC biasing of the input signal is required. Overall, the TLE2071IDG4 is a robust choice for engineers seeking high-performance operational amplifiers in demanding applications.
