FEATURES
DESCRIPTION
•
•
•
The LHV870 is an ultra-low distortion, low noise, high
slew rate operational amplifier optimized and fully
specified for high performance, high voltage
applications. Combining advanced leading-edge
process technology with state-of-the-art circuit
design, the LHV870 operational amplifier delivers
superior signal amplification for outstanding
performance. The LHV870 combines extremely low
voltage noise density (2.7nV/√Hz) with vanishingly
low DC Gain Linearity Error (0.000009%) to easily
satisfy the most demanding applications. To ensure
that the most challenging loads are driven without
compromise, the LHV870 has a high slew rate of
±20V/μs and an output current capability of ±26mA.
Further, dynamic range is maximized by an output
stage that drives 2kΩ loads to within 1V of either
power supply voltage and to within 1.4V when driving
600Ω loads.

The LHV870's outstanding CMRR (120dB), PSRR
(120dB), and VOS (0.1mV) give the amplifier excellent
DC performance.
The LHV870 operates over a wide supply range of
±2.5V to ±22V and is unity gain stable. This
operational amplifier achieves outstanding AC
performance while driving complex loads with values
as high as 100pF.
The LHV870 is available in 10-lead WQFN package.

“Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of
device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or
other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating
Conditions indicate conditions at which the device is functional and the device should not be operated beyond such conditions. All
voltages are measured with respect to the ground pin, unless otherwise specified.
The Electrical Characteristics tables list ensured specifications under the listed Recommended Operating Conditions except as
otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and
are not ensured.
If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature,
TA. The maximum allowable power dissipation is PDMAX = (TJMAX - TA) / θJA or the number given in Absolute Maximum Ratings,
whichever is lower.
