3 Description
The OPA314 family of single-, dual-, and quad-
channel operational amplifiers 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 V_S) combined
with a wide bandwidth of 3 MHz, and very low noise
(14 nV/√Hz at 1 kHz) make this 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 MΩ source impedances.
The robust design of the OPA314 devices 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).
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), and are specified over the full extended
temperature range of –40°C to 125°C.
The OPA314 (single) is available in both SC70-5 and
SOT23-5 packages. The OPA2314 (dual) is offered in
SO-8, MSOP-8, and DFN-8 packages. The quad-
channel OPA4314 is offered in a TSSOP-14 package.
