The OPA314 family of single-, dual-, and quad-channel operational amplifiers represents a
new generation of low-power, general-purpose CMOS amplifiers. Rail-to-rail input and output swings,
low quiescent current (150 µA typically at 5 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 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 pF, an 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 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 quad-channel OPA4314 is offered in a TSSOP-14
package.
