LF398 Datasheet Sample-and-hold Amplifiers

Manufacturer: NXP Semiconductors

Overview: Philips Semiconductors Linear Products Product specification Sample-and-hold amplifiers.

General Description

The LF198/LF298/LF398 are monolithic sample-and-hold circuits which utilize high-voltage ion-implant JFET 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 6µs to 0.01%.

A bipolar input stage is used to achieve low offset voltage and wide bandwidth.

Key Features

  • Operates from ±5V to ±18V supplies.
  • Less than 10µs acquisition time.
  • TTL, PMOS, CMOS compatible logic input.
  • 0.5mV typical hold step at CH=0.01µF.
  • 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.
