OPA348 Datasheet, PDF (3/19 Pages) Texas Instruments – 1MHz, 45UA, CMOS, Rail-to-Rail OPERATIONAL AMPLIFIERS

ELECTRICAL CHARACTERISTICS: V_S = 2.5V to 5.5V
Boldface limits apply over the specified temperature range, T_A = –40°C to +125°C
At T_A = +25°C, R_L = 100kΩ connected to V_S / 2 and V_OUT = V_S / 2, unless otherwise noted.
