Overview

The LF198/LF298/LF398 are monolithic sample-and-hold circuits which utilize BI-FET technology to obtain ultra-high dc accuracy with fast acquisition of signal and low droop rate. Operating as a unity gain follower, dc gain accuracy is 0.002% typical and acquisition time is as low as 6 µs to 0.01%.

  • Operates from ±5V to ±18V supplies
  • Less than 10 µs acquisition time
  • TTL, PMOS, CMOS compatible logic input
  • 0.5 mV typical hold step at Ch = 0.01 µF
  • Low input offset
  • 0.002% gain accuracy
  • Low output noise in hold mode
  • Input characteristics do not change during hold mode
  • High supply rejection ratio in sample or hold
  • Wide bandwidth
