NOTES: (1) The negative sign indicates input bias current flows out of the input terminals. (2) Output voltage swings are measured between the output and power supply rails. SPECIFICATIONS: VS = ±15V At TA = +25°C, RL = 100kΩ connected to ground, unless otherwise noted. Boldface limits apply over the specified temperature range, TA = –40°C to +85°C.
