The OPAx316-Q1 family of single and dual operational amplifiers represents a new generation of general-purpose, low-power operational amplifiers. Featuring rail-to-rail input and output swings, low quiescent current (400 µA/ch typical) combined with a wide bandwidth of 10 MHz and very-low noise (11 nV/√Hz at 1 kHz) makes this family suitable for circuits requiring a good speed and power ratio. The low input bias current supports those operational amplifiers for applications with megaohm source impedances. The low input bias current of the OPAx316-Q1 yields a very-low current noise to make the device attractive for high impedance sensor interfaces.
The robust design of the OPAx316-Q1 provides ease-of-use to the circuit designer: a unity-gain stable, integrated RFI and EMI rejection filter, no phase reversal in overdrive condition, 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). This latest addition of low-voltage CMOS automotive grade operational amplifiers provide a family of wide bandwidth, low noise, and low power that meet the needs of a wide variety of applications.
