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 V_OS (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.
