With a supply voltage specified from 2 to 5 V, this comparator can operate over a wide temperature range: - C to 125 C. The TS22 comparator offers micropower consumption as low as a few tens of microamperes thus providing an excellent ratio of power consumption current versus response time. The TS22 includes push-pull outputs and is available in small packages (SMD): SO-8 and MiniSO-8. December 17 DocID159 Rev 3 1/19 This is information on a product in full production.

13 TS22 Application recommendation 4 Application recommendation When high speed comparators are used, it is strongly recommended to place a capacitor as close as possible to the supply pins. Decoupling has two main advantages for this application: it helps to reduce electromagnetic interference and rejects the ripple that may appear on the output. A bypass capacitor combination, composed of nf in addition to 10 nf and 1 nf in parallel is recommended because it eliminates spikes on the supply line better than a single nf capacitor. Each millimeter of the PCB track plays an important role. Bypass capacitors must be placed as close as possible to the comparator supply pin. The smallest value capacitor should be preferably placed closer to the supply pin. In addition, important values of input impedance in series with parasitic PCB capacity and input comparator capacity create an additional RC filter. It generates an additional propagation delay. For high speed signal applications, PCB must be designed with great care taking into consideration low resistive grounding, short tracks and quality SMD capacitors featuring low ESR. Bypass capacitor stores energy and provides a complementary energy tank when spikes occur on the power supply line. If the input signal frequency is far from the resonant frequency, impedance strongly increases and the capacitor loses bypassing capability. Placing different capacitors with different resonant frequencies allows a wide frequency bandwidth to be covered. It is also recommended to implement an unbroken ground plane with low inductance.
