Ces amplificateurs fonctionnent sur une alimentation de 1,8 V \u00e0 5,25 V, pr\u00e9sentent des entr\u00e9es et sorties rail-\u00e0-rail, et comprennent des versions avec mode arr\u00eat, ce qui r\u00e9duit encore la consommation d\u2019\u00e9nergie pendant les p\u00e9riodes d\u2019inactivit\u00e9. La tension de d\u00e9calage de z\u00e9ro d\u2019entr\u00e9e est de seulement 400 \u00b5V maximum. Ils sont sp\u00e9cifi\u00e9s sur les gammes de temp\u00e9ratures industrielles I de -40 \u00b0C \u00e0 +85 \u00b0C et plus \u00e9tendues H de -40 \u00b0C \u00e0 +125 \u00b0C.<\/p>\n

Avec un courant d\u2019alimentation de seulement 20 \u00b5A par amplificateur, les LTC6258\/59\/60 r\u00e9alisent un produit gain-bande passante de 1,3 MHz et une vitesse de balayage de 240 V\/ms. Ils incluent les filtres d\u2019entr\u00e9e contre les interf\u00e9rences \u00e9lectromagn\u00e9tiques (EMI) qui procurent une r\u00e9jection de 45 dB \u00e0 1 GHz. En outre, ils sont stables \u00e0 n\u2019importe quel gain et n\u2019importe quelle charge capacitive.
\nLes LTC6261\/62\/63 r\u00e9alisent un produit gain-bande passante de 30 MHz et une vitesse de balayage de 7 V\/ms, consommant juste 240 \u00b5A par amplificateur. Le niveau de bruit en tension, dans la bande passante est de seulement 13 nV\/\u00d6Hz.  Ils sont stables \u00e0 n\u2019importe quel gain et n\u2019importe quelle charge capacitive jusqu\u2019\u00e0 1 nF.<\/p>\n

Les mod\u00e8les simples LTC6258 et 61 sont propos\u00e9s en bo\u00eetier DFN \u00e0 encombrement r\u00e9duit de seulement 2 x 2 mm. Les doubles LTC6259 et 62 sont encapsul\u00e9s dans un bo\u00eetier DFN de la m\u00eame taille, ainsi que dans les bo\u00eetiers SOT-23 de 8 broches, MSOP-8 et MSOP-10 avec mode arr\u00eat. Les versions quadruples LTC6260 et 63 sont, quant \u00e0 elles, pr\u00e9sent\u00e9es en bo\u00eetier MSOP-16.<\/p>\n
