The LF398M from Texas Instruments is a monolithic sample-and-hold circuit utilizing BI-FET technology for ultrahigh DC accuracy and fast acquisition. It operates with supply voltages from ±5V to ±18V and offers an acquisition time as low as 6 µs to 0.01%. The device boasts a typical gain accuracy of 0.002% when operating as a unity-gain follower and a typical hold step of 0.5 mV at 0.01 µF.
Logic inputs are compatible with TTL, PMOS, and CMOS levels. The input impedance is a high 10 GΩ, allowing for high-source impedances without accuracy degradation. In hold mode, the output noise is low, and input characteristics remain stable. The wide bandwidth permits integration within the feedback loop of 1-MHz operational amplifiers without stability issues.
The LF398M is available in SOIC (14-pin) and PDIP (8-pin) packages. It operates within a temperature range of 0°C to 70°C.
