Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: The inputs are protected by back-to-back diodes as well as ESD

protection diodes to each power supply. If the differential input voltage

exceeds 1.4V or the input extends more than 500mV beyond the power

supply, the input current should be limited to less than 10mA.

Note 3: A heat sink may be required to keep the junction temperature

below the absolute maximum rating when the output is shorted

indefinitely.

Note 4: LTC6258I/LTC6259I/LTC6260I and LTC6258H/LTC6259H/

LTC6260H are guaranteed functional over the temperature range of

–40°C to 125°C.

1.8V ELECTRICAL CHARACTERISTICS The

denotes the specifications which apply over the full

operating temperature range, otherwise specifications are at TA = 25°C. VSUPPLY = 1.8V, VCM = VOUT = 0.4V, CL = 10pF, VSHDN is

unconnected.

Note 5: The LTC6258I/LTC6259I/LTC6260I are guaranteed to meet

specified performance from –40°C to 85°C. The LTC6258H/LTC6259H/

LTC6260H are guaranteed to meet specified performance from –40°C to

125°C.

Note 6: Thermal resistance varies with the amount of PC board metal

connected to the package. The specified values are for short traces

connected to the leads.

Note 7: The input bias current is the average of the currents into the

positive and negative input pins.

Note 8: Full power bandwidth is calculated from the slew rate FPBW =

SR/π • VP-P.
