LF198-X

The LF198-X/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 s to 0.01%. A bipolar input stage is used to achieve low offset voltage and wide bandwidth.

Features of the LF198-X are:(1)Operates from ±5V to ±18V supplies; (2) Less than 10 s acquisition time; (3) TTL, PMOS, CMOS compatible logic input; (4) 0.5 mV typical hold step at Ch = 0.01 F; (5) Low input offset; (6) 0.002% gain accuracy; (7) Low output noise in hold mode; (8) Input characteristics do not change during hold mode; (9)High supply rejection ratio in sample or hold; (10)Wide bandwidth; (11) Space qualified, JM38510.

The absolute maximum ratings of the LF198-X can be summarized as:(1)Supply Voltage : ±18V;(2)Input Voltage : Equal to Supply Voltage;(3)Output Short Circuit Duration: Indefinite; (4)Power Dissipation: 500mW;(5)storage temperature:-65°C to +150°C;(6)Operating Temperature :-55 to 125°C.
