LT1638/LT1639 1.2MHz, 0.4V/s Over-The-Top Micropower Rail-to-Rail Input and Output Op Amps DESCRIPTIO
The LT ®1638 is a low power dual rail-to-rail input and output operational amplifier available in the standard 8-pin PDIP and SO packages as well as the 8-lead MSOP package.
The LT1639 is a low power quad rail-to-rail input and output operational amplifier offered in the standard 14-pin PDIP and surface mount packages. For space limited applications the LT1638 is available in a 3mm x 3mm x 0.8mm dual fine pitch leadless package (DFN). The LT1638/LT1639 op amps operate on all single and split supplies with a total voltage of 2.5V to 44V drawing only 170A of quiescent current per amplifier. These amplifiers are reverse battery protected and draw no current for reverse supply up to 18V. The input range of the LT1638/LT1639 includes both supplies, and a unique feature of this device is its capability to operate over the top with either or both of its inputs above V
