The LF398N/NOPB is a monolithic sample & hold amplifier manufactured by Texas Instruments. It consists of a low-cost, low-power, operational amplifier buffer and a precision analog switch to control the tracking and hold time constants. The LF398N/NOPB has a wide operating temperature range (-55°C to +125°C), low distortion, low gain drift, and fast settling time. It also has a very low noise performance that makes it ideal for low-noise, low-distortion, high-fidelity audio applications. The LF398N/NOPB is available in a small 8-pin package, making it easy to integrate into various systems. In addition, it features a wide supply voltage range (3V to 32V) allowing it to be used in both single and dual supply operational amplifiers without any modifications.
