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. If any of

the input or shutdown pins goes 300mV beyond either supply or the

differential input voltage exceeds 1.4V the input current should be limited

to less than 10mA. This parameter is guaranteed to meet specified

performance through design and/or characterization. It is not production

tested.

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

below the absolute maximum rating when the output current is high. This

parameter is guaranteed to meet specified performance through design

and/or characterization. It is not production tested.

Note 4: The LTC6253-7I is guaranteed to meet specified performance

from –40°C to 85°C. The LTC6253-7H is guaranteed to meet specified

performance from –40°C to 125°C.

Note 5: Supply voltage range is guaranteed by power supply rejection

ratio test.

Note 6: The input bias current is the average of the average of the currents

at the positive and negative input pins.

Note 7: Matching parameters are the difference between the two amplifiers

on the LTC6253-7.

Note 8: Thermal resistance varies with the amount of PC board metal

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

connected to the leads with minimal metal area.

Note 9: The output voltage is varied from 0.5V to 4.5V during

measurement.

supply.

Note 11: The output voltage is varied from 0.5V to 2.2V during

measurement.

Note 12: FPBW is determined from distortion performance in a gain of +7

configuration with HD2, HD3 < –40dBc as the criteria for a valid output.
