DESCRIPTION

The AO1313 is single channel op amps represents a

new generation of low cost, general purpose,

micro-power operational amplifiers. Feature rail-to-rail

input and output swings and low quiescent current

(75uA, typ. at 5V) combined with a wide

gain-bandwidth product of 1MHz and very low noise

(27nV/ Hz at 1kHz) , a slew rate of 0.8V/μs makes

AO1313 very attractive for a variety of battery-power

applications that require an optimal performance in

low voltage and low noise systems.

AO1313 provides rail-to-rail output swing into heavy

loads, RF/EMI rejection filter and high electrostatic

discharge (ESD) protection (6-kV HBM). The AO1313

input common mode voltage range includes ground,

and the maximum input offset voltage is 3.5mV.

The AO1313 are optimized for operation at voltages

as low as +1.8V and up to +6V and are specified over

the extended industrial temperature range (-40℃ to

+125℃).

The AO1313 is available in SOT-25 and SC70-5

packages.
