The LF398M/NOPB is a monolithic sample and hold circuit from Texas Instruments, utilizing BI-FET technology for high DC accuracy and low droop rate. It operates from ±5-V to ±18-V supplies and features 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.
With a bipolar input stage, the LF398M/NOPB achieves low offset voltage and wide bandwidth, allowing it to be integrated into feedback loops of 1-MHz operational amplifiers without stability issues. The input impedance is 10 GΩ. The input characteristics do not change during hold mode, and it offers a high supply rejection ratio in both sample and hold modes.
This component is available in a 14-pin SOIC package and operates within a temperature range of 0°C to 70°C. It is compatible with TTL, PMOS, and CMOS logic inputs.
