The LF398-N is a monolithic sample-and-hold circuit designed by Texas Instruments, utilizing BI-FET technology to achieve high DC accuracy and fast signal acquisition. It operates with a typical DC gain accuracy of 0.002% and an acquisition time as low as 6 µs to 0.01%. The device features a low input offset voltage and a high input impedance of 10^10 Oc, making it suitable for high-source impedances without compromising accuracy. The LF398-N supports a wide supply voltage range from ±5 V to ±18 V and is compatible with TTL, PMOS, and CMOS logic levels. It exhibits low droop rates of 5 mV/min with a 1 µF hold capacitor and ensures minimal feedthrough during hold mode. The device is available in multiple package options, including PDIP and SOIC, and is suitable for applications such as ramp generators, integrators, and synchronous correlators.
