3 Description
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.
