OPA2314AIDR

3 MHz的低功耗，低噪声， RRI / O， 1.8 V CMOS运算放大器 3-MHz, Low-Power, Low-Noise, RRI/O, 1.8-V CMOS OPERATIONAL AMPLIFIER

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.
