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.
