The LFx98x devices are monolithic sample-and-hold circuits that use BI-FET technology toobtain ultrahigh DC accuracy with fast acquisition of signal and low droop rate. Operating as aunity-gain follower, DC gain accuracy is 0.002% typical and acquisition time is as low as 6 μs to0.01%. A bipolar input stage is used to achieve low offset voltage and wide bandwidth. Input offsetadjust is accomplished with a single pin and does not degrade input offset drift. The widebandwidth allows the LFx98x to be included inside the feedback loop of 1-MHz operational amplifierswithout having stability problems. Input impedance of 1010 Ω allowshigh-source impedances to be used without degrading accuracy.

P-channel junction FETs are combined with bipolar devices in the output amplifier to givedroop rates as low as 5 mV/min with a 1-μF hold capacitor. The JFETs have much lower noise than MOSdevices used in previous designs and do not exhibit high temperature instabilities. The overalldesign ensures no feedthrough from input to output in the hold mode, even for input signals equalto the supply voltages.

Logic inputs on the LFx98x are fully differential with low input current, allowing fordirect connection to TTL, PMOS, and CMOS. Differential threshold is 1.4 V. The LFx98x will operate from ±5-V to ±18-V supplies.

An A version is available with tightened electrical specifications.
