The THS4541IRUNR is a single-channel differential amplifier from Texas Instruments built for high-speed signal chains. Its defining spec is the 1500 V/µs slew rate, paired with a 620 MHz -3 dB bandwidth and 850 MHz gain-bandwidth product.
Industrial temperature range — not just a commercial part
The 100 µV input offset and 12 µA input bias are stable enough across temperature that you won't need a trim pot in most ADC interface designs. The 10.1 mA supply current is the trade-off for the speed — it's not a low-power part, but for a 620 MHz differential amp the current is in line with the class.
2x2 mm footprint — layout reality
The 10-WQFN (2x2 mm) package sits close to the ADC input pins, preserving signal integrity at 620 MHz.
