DESCRIPTION
The OPA313 family of single-, dual-, and quad-
channel op amps represents a new generation of low-
cost, general purpose, micro-power operational
amplifiers. Featuring rail-to-rail input and output
swings, and low quiescent current (50 μA, typ)
combined with a wide bandwidth of 1 MHz and very
low noise (25 nV/√Hz at 1 kHz) makes this family
very attractive for a variety of battery-powered
applications that require a good balance between
cost and performance. The low input bias current
supports those op amps to be used in applications
with megaohm source impedances.
The robust design of the OPA313 devices provides
ease-of-use to the circuit designer: unity-gain stability
with capacitive loads of up to 150 pF, integrated
RF/EMI rejection filter, no phase reversal in overdrive
conditions, and high electrostatic discharge (ESD)
protection (4-kV HBM).
These devices are optimized for operation at voltages
as low as +1.8 V (±0.9 V) and up to +5.5 V (±2.75 V),
and are specified over the extended temperature
range of –40°C to +125°C.
The OPA313 (single) is available in both SC70-5 and
SOT23-5 packages. The OPA2313 (dual) is offered in
SO-8, MSOP-8, and DFN-8 packages. The quad-
channel OPA4313 is offered in a TSSOP-14 package.
