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 150Ω.
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.
