A 100 kHz gain-bandwidth product means the TS27L4CDT is comfortable with closed-loop gains up to 100 at 1 kHz, but unity-gain bandwidth stops at 100 kHz. For a 10× gain stage, expect a -3 dB bandwidth around 10 kHz.
The TS27L4CDT operates from 3 V to 16 V single supply. Each output can source or sink 45 mA.
Yes, each of the four channels draws only 10 µA of supply current, totalling 40 µA for the full package. That places it firmly in the micropower category, suitable for battery-powered and always-on sensor front-ends.
The closest functional peer is the TS27L2IDT, a dual-channel version with the same 100 kHz GBW, 0.04 V/µs slew rate, and 1 pA input bias, but in a wider -40°C to 125°C temperature range. For a quad-channel part with higher speed (3.5 MHz GBW, 5.5 V/µs slew rate) at the cost of higher supply current (1 mA per channel), consider the TS274IPT.
