OPA341,OPA2341: Single-Supply, Rail-to-Rail Op
... The OPA341 series operate on a single supply as low as 2.5V, and input common-mode voltage range extends 300mV beyond the supply rails. Output voltage swings to within 1mV of the supply rails with a 100kΩ load. The OPA341 series offers excellent dynamic response (BW = 5.5MHz, SR = 6V/µs) with a quie ...
