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.
