3 Description

The TLV314 family of single-, dual-, and quadchannel

operational amplifiers represents a new

generation of low-power, general-purpose operational

amplifiers. Rail-to-rail input and output swings

(RRIO), low quiescent current (150 μA typically at

5 V) combine with a wide bandwidth of 3 MHz to

make this family very attractive for a variety of

battery-powered applications that require a good

balance between cost and performance. Additionally,

the TLV314 family architecture achieves a low input

bias current of 1 pA, allowing for applications with MΩ

source impedances.

The robust design of the TLV314 devices provides

ease-of-use to the circuit designer: unity-gain stability,

RRIO, 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 extended

industrial temperature range of –40°C to +125°C.

The TLV314 (single) is available in both 5-pin SC70

and SOT-23 packages. The TLV2314 (dual) is offered

in 8-pin SOIC and VSSOP packages. The quadchannel

TLV4314 is offered in a 14-pin TSSOP

package.
