The recommended operating voltage range for the LF198AH/NOPB is 4.5V to 16V.
To ensure stability, it is recommended to use a minimum gain of 5, and to avoid capacitive loads. Additionally, a 10nF to 100nF capacitor can be added between the output and the inverting input to improve stability.
The maximum output current of the LF198AH/NOPB is 20mA.
While the LF198AH/NOPB can be used as a comparator, it is not recommended due to its op-amp architecture. Texas Instruments recommends using a dedicated comparator like the LM339 or LM2901 for comparator applications.
To reduce noise, use a low-pass filter at the input, keep the circuit layout clean and compact, and use a decoupling capacitor (e.g., 10uF) between the power supply pins.
