The OPAx314-Q1 series is a family of single-, and dual-, and quad-channel operational amplifiers (op-amps) that 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 device 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 OPAx314-Q1 series 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).

The 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 +125°C.

The single-channel device, OPA314-Q1, is offered in the SOT-23 package and the dual-channel device, OPA2314-Q1, is offered in the VSSOP (8) package. The quad-channel OPA4314-Q1 is available in the 14-pin TSSOP package.
