Low IQ: 50 µA/ch
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
Wide Supply Range: 1.8 V to 5.5 V
Low Noise: 25 nV/√Hz at 1 kHz
Gain Bandwidth: 1 MHz
Low Input Bias Current: 0.2 pA
Low Offset Voltage: 0.5 mV
Unity-Gain Stable
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.
Internal RF/EMI Filter
Extended Temperature Range:
–40°C to +125°C
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).
