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: 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 LT6203X is guaranteed to meet specified performance from

–40°C to 175°C.

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

of the LT6203X. 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 6: Minimum supply voltage is guaranteed by power supply rejection

ratio test.

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

power supply rails.

Note 8: This parameter is not 100% tested.

Note 9: Full-power bandwidth is calculated from the slew rate:

FPBW = SR/2πVP

Note 10: 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°.

The l denotes the specifications which apply over –40°C < TA < 175°C

temperature range. VS = ±5V; VCM = VOUT = 0V, unless otherwise noted. (Note 4)
