10 MHz GBW, 45 V/µs slew — why the dynamic spec matters
The TLE2072AQDRG4Q1: Its 10 MHz gain-bandwidth product and 45 V/µs slew rate target signal-conditioning chains that need to preserve fast edge rates — think throttle-position sensor outputs, resolver excitation, or high-frequency filter stages in engine-control modules. The JFET input stage keeps input bias current at 20 pA, which means minimal voltage drop across high-impedance source resistors and less drift over temperature.
The TLE2072AQDRG4Q1 operates from a single supply as low as 4.5 V up to 38 V. Each of the two channels can source or sink 48 mA. Supply current is 3.1 mA per amplifier. The 700 µV input offset voltage (max) is typical for a JFET design.
JFET input stage — 20 pA bias current, high-impedance sensor interface
The JFET input stage gives the TLE2072AQDRG4Q1 an input bias current of just 20 pA, which is several orders of magnitude lower than a bipolar-input op-amp. The trade-off is higher voltage noise than a bipolar design, but for slow or DC-coupled automotive sensors, the JFET's low bias drift over temperature often wins.
