3 Description
The OPA2314-Q1 device is a dual-channel
operational amplifier (op-amp) that represents a new
generation of low-power, general-purpose CMOS
amplifiers. Rail-to-rail input and output swings, low
quiescent current (150 μA typ at 5 VS) combined with
a wide bandwidth of 3 MHz, and very low noise (14
nV/âHz at 1 kHz) make this device 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
mega-ohm source impedances.
The robust design of the OPA2314-Q1 device
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).
The device is optimized for low-voltage operation as
low as 1.8 V (±0.9 V) and up to 5.5 V (±2.75 V), and
is specified over the full extended temperature range
of â40°C to 125°C.
The device is offered in an SO-8 package.
