Texas Instruments OPA313
The OPA313 family of single-, dual-, and quadchannel op amps represents a new generation of lowcost, 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.| Part No. | OPA313 |

DESCRIPTION
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.
