1 RAIL TO RAIL CMOS DUAL OPERATIONAL AMPLIFIER RAIL TO RAIL INPUT AND OUTPUT OLT- AGE RANGES SINGLE (OR DUAL) SUPPLY OPERATION FROM.7 TO 16 EXTREMELY LOW INPUT BIAS CURRENT : 1pA typ LOW INPUT OFFSET OLTAGE : m max. SPECIFIED FOR 6Ω AND Ω LOADS LOW SUPPLY CURRENT : µa/ampli ( = ) LATCH-UP IMMUNITY ESD TOLERANCE : K SPICE MACROMODEL INCLUDED IN THIS- SPECIFICATION DESCRIPTION The is a RAIL TO RAIL CMOS dual operational amplifier designed to operate with a single or dual supply voltage. The input voltage range icm includes the two supply rails + and -. At, the output reaches : - +m + -m with R L = kω - +m + -m with This product offers a broad supply voltage operating range from.7 to 16 and a supply current of only =. Source and sink output current capability is typically ma at =, fixed by an internal limitation circuit.
