Operating as 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. Input offset adjust is accomplished with a single pin and does not degrade input offset drift. The wide bandwidth allows the LF198-N to be included inside the feedback loop of 1MHz operational amplifiers without having stability problems. Input impedance of 10¹⁰Ω allows high-source impedances to be used without degrading accuracy. P-channel junction FETs are combined with bipolar devices in the output amplifier to give droop rates as low as 5mV\/minute with a 1µF hold capacitor. The JFETs have much lower noise than MOS devices used in previous designs and do not exhibit high temperature instabilities.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLow input offset\u003c\/li\u003e\n\u003cli\u003eLow output noise in hold mode\u003c\/li\u003e\n\u003cli\u003eInput characteristics do not change during hold mode\u003c\/li\u003e\n\u003cli\u003eHigh supply rejection ratio in sample or hold\u003c\/li\u003e\n\u003cli\u003eWide bandwidth\u003c\/li\u003e\n\u003cli\u003eLogic input compatible with TTL, PMOS and CMOS\u003c\/li\u003e\n\u003cli\u003e0.5mV Typical hold step at 0.01µF\u003c\/li\u003e\n\u003cli\u003e0.002% Gain accuracy\u003c\/li\u003e\n\u003cli\u003e500mW Power dissipation\u003c\/li\u003e\n\u003cli\u003e±15V Supply voltage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eIndustrial\u003c\/p\u003e\n\u003ch3\u003eWarnings\u003c\/h3\u003e\n\u003cp\u003eDevice has limited built-in ESD protection.
