That slew rate matters when you're driving a fast ADC input, reconstructing a waveform, or buffering a signal that needs clean edges without slew-induced distortion. Input offset is trimmed to 200 µV, bias current runs 700 nA, and the output can source or sink 50 mA per channel, so it handles moderate loads without a separate buffer stage.
The Excalibur designation means TI screens this variant to tighter limits than the commercial-grade TLE2141CD, so you get consistent parametric behavior across the temperature sweep without cherry-picking lots.
Supply span: 4 V to 44 V
Operates from a single or split supply spanning 4 V to 44 V. That 44 V max covers 24 V industrial rails with margin, 28 V avionics buses, and ±15 V analog supplies. Quiescent current is 3.5 mA typical — not a micropower part, but reasonable for a 5.9 MHz amplifier that can deliver 50 mA output.
ROHS3 compliant per the manufacturer's statement.
