Note 7: Full-power bandwidth is calculated from the slew rate

measurement:

FPBW = SR/2

πVP.

Note 8: Settling time measurement techniques are shown in “Take the

Guesswork Out of Settling Time Measurements,” EDN, September 19,

1985.

Note 9: NTSC (3.58MHz).

Note 10: See Applications section for shutdown at elevated temperatures.

Do not operate the shutdown above TJ > 125°C.

Note 11: AC parameters are 100% tested on the ceramic and plastic DIP

packaged parts (J and N suffix) and are sample tested on every lot of the

SO packaged parts (S suffix).

Note 1: Absolute Maximum Ratings are those values beyond which the

life of a device may be impaired.

Note 2: A heat sink is required to keep the junction temperature below

absolute maximum when the output is shorted.

Note 3: When RL = 1k is specified, the load resistor is RFB1 + RFB2, but

when RL = 100Ω is specified, then an additional 100Ω is added to the

output.

Note 4: VOS measured at the output (Pin 6) is the contribution from both

input pair, and is input referred.

Note 5: VIN LIM is the maximum voltage between –VIN and +VIN (Pin 2 and

Pin 3) for which the output can respond.

Note 6: Slew rate is measured between

±2V on the output, with a ±1V

input step, AV = 3.

ELECTRICAL CHARACTERISTICS

The q denotes the specificatons which apply over the full operating temperature range of 0

°C ≤ TA ≤ 70°C. VS = ±5V, VREF = 0V,

RFB1 = 900Ω from Pins 6 to 8, RFB2 = 100Ω from Pin 8 to ground, RL = RFB1 + RFB2 = 1k (Note 3), CL ≤ 10pF, Pin 5 open circuit,

unless otherwise noted.
