3 Description
The OPAx316 family of single, dual, and quad
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 attractive for
a variety of applications that require a good balance
between cost and performance. The low input bias
current supports those operational amplifiers to be
used in applications with MΩ source impedances.
The robust design of the OPAx316 provide ease-ofuse
to the circuit designer—a unity-gain stable,
integrated RFI-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
operational amplifiers, in conjunction with the
OPAx313 and OPAx314 provide a family of
bandwidth, noise, and power options to meet the
needs of a wide variety of applications.
