FEATURES

DESCRIPTION

The OPA314 family of single-, dual-, and quad-

•

Low I_Q: 150 µA/ch

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 typ at 5.0 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

Wide Supply Range: 1.8 V to 5.5 V

Low Noise: 14 nV/√Hz at 1 kHz

Gain Bandwidth: 3 MHz

Low Input Bias Current: 0.2 pA

Low Offset Voltage: 0.5 mV

Unity-Gain Stable

require

good balance between cost and

performance. The low input bias current supports

applications with mega-ohm source impedances.

Internal RF/EMI Filter

Extended Temperature Range:

–40°C to +125°C

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).

APPLICATIONS

•

Battery-Powered Instruments:

–

Consumer, Industrial, Medical

Notebooks, Portable Media Players

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.
