ELECTRICAL CHARACTERISTICS: V_S = ±50V
Boldface limits apply over the specified temperature range, T_A = –40°C to +85°C.
At T_P(1) = +25°C, R_L = 4.8kΩ to mid-supply, V_CM = V_OUT = mid-supply, unless otherwise noted.

(1) T_P is the temperature of the leadframe die pad (exposed thermal pad) of the PowerPAD package.
(2) See typical characteristic curve, Offset Voltage Drift Production Distribution (Figure 14).
(3) Typical range is (V–) + 1.5V to (V+) – 1.5V.
(4) Measured using low-frequency (<10Hz) ±49V square wave. See typical characteristic curve, Current Limit vs Temperature (Figure 24).
