LT6016 and LT6017 Precision Op Amp

Linear Technology introduces the LT6016 and LT6017, dual- and quad-wide input range operational amplifiers. These amplifiers combine high-precision with the ruggedness and versatility of LTC's unique Over-the-Top architecture. Input offset voltage is 50 μV max, input bias current is 5 nA, and low-frequency noise is 0.5 μVP-P making these devices suitable for a wide range of precision industrial, automotive, and instrumentation applications.

Over-the-Top inputs provide true operation well beyond the V+ rail. The LT6016 / LT6017 function normally with inputs up to 76 V above V-, independent of whether V+ is 3 V or 50 V. Additional fault-tolerant features protect the op amps from reverse supply conditions (up to -50 V at V+), negative transients (up to -25 V at VIN), and forced output voltage with no power supplied (up to 50 V at VOUT). This robust architecture is especially useful for applications where the amplifier is at the analog interface to another board, and for high- and low-side current sensing.

The LT6016 and LT6017 are fully specified over -40°C to 85°C, -40°C to 125°C, and -55°C to 150°C temperature ranges. The dual LT6016 is available in an 8-lead MSOP package and the quad LT6017 is available in a 6 mm x 3 mm DFN package.
