Precision 50μV offset op-amp accepts wide input

Available in dual and quad versions, the LT6016 and LT6017 wide-input operational amplifiers from Linear Technology combine high precision with the ruggedness and versatility of the Over-the-Top® architecture. Input offset voltage is 50μV max, input bias current is 5nA, and low frequency noise is 0.5μVP-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 76V above V- independent of whether V+ is 3V or 50V. Additional fault tolerant features protect the op amps from reverse supply conditions (up to -50V at V+), negative transients (up to -25V at VIN), and forced output voltage with no power supplied (up to 50V 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. Summary of Features: LT6016/LT6017 Input Common Mode Range: V- to V- + 76V VOS: 50μV (Maximum) Low Power: 315μA/Amplifier CMRR, PSRR: 126dB Gain Bandwidth Product: 3.2MHz High Voltage Gain: 1000V/mV Reverse Battery Protection to 50V No Phase Reversal No Supply Sequencing Problems Operating Temperature Range: -55°C to 150°C Linear Technology
