DESCRIPTION
The OPA2830 is a dual, low-power, single-supply,
wideband, voltage-feedback amplifier designed to
operate on a single +3V or +5V supply. Operation on
±5V or +10V supplies is also supported. The input
range extends below ground and to within 1.8V of the
positive
supply.
Using
complementary
common-emitter outputs provides an output swing to
within 25mV of ground and +VS while driving 150.
High output drive current (75mA) and low differential
gain and phase errors also make it ideal for
single-supply consumer video products.
Low distortion operation is ensured by the high gain
bandwidth product (100MHz) and slew rate
(500V/µs), making the OPA2830 an ideal input buffer
stage to 3V and 5V CMOS Analog-to-Digital
Converters (ADCs). Unlike earlier low-power,
single-supply amplifiers, distortion performance
improves as the signal swing is decreased. A low
9.2nV/Hz input voltage noise supports wide dynamic
range operation.
The OPA2830 is available in an industry-standard
SO-8 package. The OPA2830 is also available in a
small MSOP-8 package. For fixed-gain and line driver
applications, consider the OPA2832.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
