ELECTRICAL CHARACTERISTICS

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

of the device may be impaired.

Note 2: Inputs are protected by back-to-back diodes and diodes to each

supply. If the inputs are taken beyond the supplies or the differential input

voltage exceeds 0.7V, the input current must be limited to less than 40mA.

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: The LT6202C/LT6202I, LT6203C/LT6203I and LT6204C/LT6204I

are guaranteed functional over the temperature range of –40

°C and 85°C.

Note 5: The LT6202C/LT6203C/LT6204C are guaranteed to meet specified

performance from 0

°C to 70°C. The LT6202C/LT6203C/LT6204C 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 LT6202I/LT6203I/LT6204I are guaranteed to meet specified

performance from –40

°C to 85°C.

Note 6: Matching parameters are the difference between the two amplifiers

A and D and between B and C of the LT6204; between the two amplifiers

of the LT6203. CMRR and PSRR match are defined as follows: CMRR and

PSRR are measured in

µV/V on the identical amplifiers. The difference is

calculated between the matching sides in

µV/V. The result is converted to

dB.

Note 7: Minimum supply voltage is guaranteed by power supply rejection

ratio test.

Note 8: Output voltage swings are measured between the output and

power supply rails.

Note 9: This parameter is not 100% tested.

Note 10: Full-power bandwidth is calculated from the slew rate:

FPBW = SR/2

πVP

Note 11: Differential gain and phase are measured using a Tektronix

TSG120YC/NTSC signal generator and a Tektronix 1780R Video

Measurement Set. The resolution of this equipment is 0.1% and 0.1

°. Ten

identical amplifier stages were cascaded giving an effective resolution of

0.01% and 0.01

°.
