ELECTRICAL CHARACTERISTICS: VS = +2.7V TO +5.5V

BOLDFACE limits apply over the specified temperature range, TA = –55°C TO +125°C

At TA = +25°C, RL = 10kΩ, G = 25, and VCM = VS /2, unless otherwise noted.

NOTES: (1) Does not include errors from external gain setting resistors.

(2) Output voltage swings are measured between the output and power-supply rails. Output swings to rail only if G

≥ 10. Output does not swing to

positive rail if gain is less than 10.

(3) See typical characteristic curve,

Percent Overshoot vs Load Capacitance.

(4) See typical characteristic curve,

Shutdown Voltage vs Supply Voltage.
