Rail-to-rail input and output swings, low quiescent current (150 μA typically at 5 VS) bined with a wide bandwidth of 3 MHz, and very low noise (14 n V/√Hz at 1 k Hz) make 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 applications with MΩ source impedances. The robust design of the OPA314 devices provides ease-of-use to the circuit designer: unity-gain stability with capacitive loads of up to 300 p F, an integrated RF/EMI rejection filter, no phase reversal in overdrive conditions, and high electrostatic discharge (ESD) protection (4-k V HBM). These devices are optimized for low-voltage operation as low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V), and are specified over the full extended temperature range of - 40°C to 125°C. The OPA314 (single) is available in both SC70-5 and SOT23-5 packages. The OPA2314 (dual) is offered in SO-8, MSOP-8, and DFN-8 packages. The quadchannel OPA4314 is offered in a TSSOP-14 package.
