我也是今天才知道电子工程世界网站上也有技术资料可以下载啊!!!坚决支持一下!
只是我觉得查找资料不如网站的方便,也许是我习惯了在上查找资料。网站只要能够提供相关技术资料下载就会方便广大网民的需要,就会得到更多人的支持,在此基础上能做到方便快捷就好了,在每个器件的下载网页上放些摘要的想法不错,但必竟是摘要,详细的参数还是需要下载原文档去看。所以,网页上不必放太多的摘要,这样需要花费人力去做,花费网站的大量资源。更主要是很多器件的摘要是一些看不懂的字符,对下载者没有什么实际的意义,但却使网页变得零乱不堪,影响了心情。为了做这些网页,网站却要花费很多的人力,真有点得不偿失了。资料下载网页尽量做得简单明了。你们可以参见网站的做法。
如下,这是INA114器件的下载网页的摘要,太乱了!!!

INA114
DESCRIPTION
The INA114 is a low cost, general purpose instrumen-
tation amplifier offering excellent accuracy. Its versa-
tile 3-op amp design and small size make it ideal for a
wide range of applications.
A single external resistor sets any gain from 1 to 10,000.
Internal input protection can withstand up to ±40V
without damage.
The INA114 is laser trimmed for very low offset voltage
(50?V), drift (0.25?V/°C) and high common-mode
rejection (115dB at G = 1000). It operates with power
supplies as low as ±2.25V, allowing use in battery
operated and single 5V supply systems. Quiescent cur-
rent is 3mA maximum.
The INA114 is available in 8-pin plastic and SOL-16
surface-mount packages. Both are specified for the
–40°C to +85°C temperature range.
