Operating as a unity gain follower, dc gain accuracy is 0.002% typical and acquisition time is as • 0.5 mV typical hold step at Ch = 0.01 μF low as 6 μs to 0.01%. A bipolar input stage is used to • Low input offset achieve low offset voltage and wide bandwidth. Input • 0.002% gain accuracy offset adjust is accomplished with a single pin, and does not degrade input offset drift. The wide • Low output noise in hold mode bandwidth allows the LF198 to be included inside the • Input characteristics do not change during feedback loop of 1 MHz op amps without having hold mode stability problems. Input impedance of 1010 Ω allows • High supply rejection ratio in sample or hold high source impedances to be used without degrading accuracy. • Wide bandwidth P-channel junction FET's are combined with bipolar devices in the output amplifier to give droop rates as low as 5 mV/min with a 1 μF hold capacitor. The JFET's have much lower noise than MOS devices used in previous designs and do not exhibit high temperature instabilities. The overall design specifies no feed-through from input to output in the hold mode, even for input signals equal to the supply voltages. Logic inputs on the LF198 are fully differential with low input current, allowing direct connection to TTL, PMOS, and CMOS. Differential threshold is 1.4V. The LF198 will operate from ±5V to ±18V supplies. Connection Diagrams Figure 1. Small-Outline Package (CGLA) Figure 2.
