DESCRIPTION
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 uA typ at 5.0 Vs) combined with a wide bandwidth of 3 MHz, and very low noise
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 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 reiection 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 +5.5V(±2.75 V), and are specified over the full extended temperature range of-40°℃ to +125℃.
Feature
- Low IQ: 150 μA/ch
- Wide Supply Range: 1.8 V to 5.5 V
- 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.
