The l denotes the specifications which apply

over the full operating temperature range, otherwise specifications are at TA = 25°C. VS = 3V, 0V,VCM = 1.5V, VSHDN = floating unless

otherwise noted.

ELECTRICAL CHARACTERISTICS (VS = 3V, 0V)

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 0.7V, 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 current is high.

Note 4: The LTC6226I/LTC6227I are guaranteed functional and specified

over the temperature range of –40°C to 85°C. The LTC6226H/LTC6227H

are guaranteed and specified functional over the temperature range of

–40°C to 125°C.

Note 5: Matching parameters are the difference between amplifiers A and

B on the LTC6227.

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

through the positive and negative input pins.

Note 7: Supply Voltage Range is guaranteed by Power Supply Rejection

Ratio test.

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.

Note 9: Middle 2/3 of the output waveform is observed for Slew Rate.

RL = 1k to half supply.

Note 10: Input Common Mode Range is guaranteed by Common Mode

Rejection Ratio Test.
