The OPA2314 is a dual channel operational amplifier and represents a new generation of low-power, general-purpose CMOS amplifiers. Rail-to-rail input and output swings, low quiescent current (150 µA typ at 5.0 VS) combined with a wide bandwidth of 3 MHz, and very low noise (14 nV/√Hz at 1 kHz) 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 mega-ohm source impedances.
The robust design of the OPA2314 provides ease-of-use to the circuit designer: unity-gain stability with capacitive loads of up to 300 pF, an integrated RF/EMI rejection filter, no phase reversal in overdrive conditions, and high ESD protection (4-kV HBM).
This device is optimized for low-voltage operation as low as +1.8 V (±0.9 V) and up to +5.5 V (±2.75 V), and is specified over the full extended temperature range of ±40°C to +150°C.
The OPA2314 (dual) is offered in a DFN-8 package.
