ELECTRICAL CHARACTERISTICS The q denotes specifications which apply over the specified temperature

range, otherwise specifications are at TA = 25°C. VS = ±5V; VCM = VOUT = 0V, unless otherwise noted.

Note 1: Absolute Maximum ratings are those values beyond which the life

of a device may be impaired.

Note 2: The inputs are protected by back-to-back diodes. If the differential

input voltage exceeds 1.4V, the input current should be limited to less than

10mA.

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

below absolute maximum. This depends on the power supply voltage and

how many amplifiers are shorted.

Note 4: The LT6205C/LT6206C/LT6207C are guaranteed to meet specified

performance from 0

°C to 70°C and are designed, characterized and

expected to meet specified performance from –40

°C to 85°C but are not

tested or QA sampled at these temperatures. The LT6205I/LT6206I/

LT6207I are guaranteed to meet specified performance from

–40

°C to 85°C.

Note 5: Matching parameters are the difference between the two amplifiers

A and D and between B and C of the LT6207; between the two amplifiers

of the LT6206.

Note 6: This parameter is not 100% tested.

Note 7: Output voltage swings are measured between the output and

power supply rails.

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

measurement: FPBW = SR/2

πVPEAK.

Note 9: There are reverse biased ESD diodes on all inputs and outputs.

If these pins are forced beyond either supply, unlimited current will flow

through these diodes. If the current is transient in nature and limited to

less than 25mA, no damage to the device will occur.
