3 Description

The TLV313 family of single-, dual-, and quadchannel

precision operational amplifiers combine low

power consumption with good performance. This

makes them suitable for a wide range of applications,

such as wearables, utility metering, building

automation, currency counters and more. The family

features rail-to-rail input and output (RRIO) swings,

low quiescent current (65 μA, typical), wide bandwidth

(1 MHz) and very low noise (26 nV/√Hz at 1 kHz),

making it attractive for a variety of battery-powered

applications that require a good balance between

cost and performance. Further, low-input-bias current

enables these devices to be used in applications with

megaohm source impedances.

The robust design of the TLV313 devices provides

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

with capacitive loads of up to 150 pF, integrated

RF/EMI rejection filter, no phase reversal in overdrive

conditions, and high electrostatic discharge (ESD)

protection (4-kV HBM).

The devices are optimized for operation at voltages

as low as +1.8 V (±0.9 V) and up to +5.5 V (±2.75 V),

and are specified over the extended temperature

range of .40°C to +125°C.

The single-channel TLV313 device is available in

both SC70-5 and SOT23-5 packages. The dualchannel

TLV2313 device is offered in SOIC-8 and

VSSOP-8 packages, and the quad-channel TLV4313

device is offered in a TSSOP-14 package.
