A single Over-the-Top operational amplifier has been announced by Linear Technology. The new device features a very high level of precision with over a 0V to 76V input common-mode voltage range.
The device incorporates multiple built-in fault tolerant features, resulting in no-compromise performance over wide operating supply and temperature ranges.
Over-the-Top inputs provide true operation well beyond the V rail. The LT6015 functions normally with its inputs up to 76V above V-, independent of whether V+ is 3V or 50V.
Input offset voltage is 80µV max, input bias current is 5nA and low frequency noise is 0.5µVP-P, making this device suitable for a wide range of precision industrial, automotive and instrumentation applications.
Fault protection modes guard against negative transients, reverse battery and other conditions, making the LT6015 ideal fit for applications where the amplifier is at the analogue interface to another board, and for high-side and low-side current sensing.
