3 Description
The OPA2810 is a dual-channel, FET-input, voltage-
feedback operational amplifier (op amp) with
extremely low input bias current. The OPA2810 is
unity-gain stable with a small-signal unity-gain
bandwidth of 120 MHz, and offers both excellent DC
precision and dynamic AC performance at very low
quiescent power. The OPA2810 is fabricated on
Texas Instrument's proprietary, high-speed SiGe
BiCMOS process and achieves significant
performance improvements over comparable FET-
input amplifiers at similar levels of quiescent power.
With a gain-bandwidth product (GBWP) of 70 MHz,
extremely high slew-rate (240 V/µs), and very low-
noise (5.7 nV/√Hz) the OPA2810 is ideal in a wide
range of data acquisition and signal processing
applications. It achieves these benchmark levels of
performance while consuming a typical quiescent
current (I_Q) of 3.6 mA /channel.
The OPA2810 is characterized to operate over a wide
supply range of 4.75 V to 27 V, and features rail-to-
rail inputs and outputs. The wide supply-range and
excellent dynamic performance of the OPA2810
device makes it well suited for a wide range of
applications, such as wideband photodiode
transimpedance amplifiers, test and measurement
front end buffers, active filters, impedance
measurement systems, power analyzers, as well as
general purpose gain and level-shifting stages. The
OPA2810 amplifier is capable of delivering 50 mA of
linear output current, and is therefore suitable for
driving optoelectronics components and buffering
DAC outputs into heavy loads.
The OPA2810 is available in an 8-pin, SOT23-8 and
VSSOP-8 package and is rated to work over the
extended industrial temperature range of –40°C to
+125°C.
