DESCRIPTION
The OPA378 and OPA2378 represent a new
generation of micropower operational amplifiers.
Rail-to-rail input, low input offset voltage (50µV max),
low quiescent current (125µA max), and 900kHz
bandwidth make this part very attractive for
low-power precision applications. In addition, this part
has excellent PSRR, making it an outstanding choice
for applications that run directly from batteries without
regulation.
The OPA378 (single version) is available in a
microSIZE SC70-5 and SOT23-5. The OPA2378
(dual version) is offered in s SOT23-8 package. All
versions are specified for operation from –40°C to
+125°C.
