Dual/Quad Operational Amplifiers: LT6016 / LT6017

February 14, 2013


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 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-side 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, starting at $2.50 each in quantities of 1000. The quad LT6017 is available in a 6mm x 3mm DFN package, starting at $3.96 each in quantities of 1000.
