OPA344 Datasheet, PDF (3/29 Pages) Burr-Brown (TI) – LOW POWER, SINGLE-SUPPLY, RAIL-TO-RAIL OPERATIONAL AMPLIFIERS MicroAmplifier ™ Series

SPECIFICATIONS: V_S = 2.7V to 5.5V
At T_A = +25°C, R_L = 10kΩ connected to V_S /2 and V_OUT = V_S /2, unless otherwise noted.
Boldface limits apply over the temperature range, T_A = –40°C to +85°C.
