3 Description
The OPAx314-Q1 series is a family of single–, and
dual–, and quad-channel operational amplifiers (op
amps) that represents a new generation of lowpower,
general-purpose CMOS amplifiers. Rail-to-rail
input and output swings, low quiescent current (150
μA typically at 5 VS) combined with a wide bandwidth
of 3 MHz, and very low noise (14 nV/√Hz at 1 kHz)
make this device family very attractive for a variety of
battery-powered applications that require a good
balance between cost and performance. The lowinput
bias current supports applications with
megaohm source impedances.
The robust design of the OPAx314-Q1 series
provides ease-of-use to the circuit designer: unitygain
stability with capacitive loads of up to 300 pF, an
integrated RF and 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 –40°C to +125°C.
The single-channel device, OPA314-Q1, is offered in
the SOT-23 package and the dual-channel device,
OPA2314-Q1, is offered in the VSSOP (8) package.
The quad-channel OPA4314-Q1 is available in the
14-pin TSSOP package.
