Sample-and-hold amplifiers

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 acquisiti

MONOLITHIC SAMPLE AND HOLD CIRCUITS

GENERAL DESCRIPTION The LF198/LF298/LF398 are BI-FET monolithic sample and hold circuits with ultra-high DC accuracy, fast acquisition time (6μ to 0.01) and low droop rate. A bipolar input stage is used to obtain the lowest possible offset voltage and wide bandwidth.

單片采樣保持電路（10μs 采集，3mV 失調(diào)電壓）

LFx98x 器件是采用 BI-FET 技術(shù)的單片采樣保持電路，利用快速采集信號(hào)和低下降率獲得超高的直流精度。作為單位增益跟隨器，直流增益精度為 0.002％（典型值），采集時(shí)間低至 6μs (0.01％)。采用雙極輸入級(jí)以實(shí)現(xiàn)低偏移電壓和寬帶寬。輸入偏移調(diào)整是通過(guò)單個(gè)引腳完成的，不會(huì)降低輸入偏移漂移。寬帶寬允許將 LFx98x 包含在 1MHz 運(yùn)算放大器的反饋環(huán)路內(nèi)，而不會(huì)出現(xiàn)穩(wěn)定性問(wèn)題。輸入阻抗為 1010Ω，允許使用高源阻抗，而不會(huì)降低精度。\n\nP 通道結(jié)型 FET 與輸出放大器中的雙極器件相結(jié)合，通過(guò) 1μF 保持電容器提供低至 5mV/min 的下降率。JFET 的噪聲顯著低于 ? 通過(guò) ±5V 至 ±18V 的電源工作\n? 采集時(shí)間少于 10μs\n? 邏輯輸入與 TTL、PMOS、CMOS 兼容\n? 在 Ch = 0.01μF 時(shí)保持步進(jìn)為 0.5mV（典型值）\n? 低輸入偏移\n? 增益精度為 0.002%\n? 在保持模式下，輸出噪聲較低\n? 在保持模式期間，輸入特點(diǎn)不變\n? 在采樣或保持模式中，電源抑制比高\(yùn)n? 寬帶寬\n? 符合太空要求，符合 JM38510;
