DESCRIPTION
The OPA4830 is a quad, 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 the negative supply and to
within 1.8V of the positive supply. Using
complementary common-emitter outputs provides an
output swing to within 220mV of either supply while
driving 150Ω. High output drive current (±80mA) and
low differential gain and phase errors also make this
amplifier an excellent choice for single-supply
consumer video products.
Low distortion operation is ensured by the high gain
bandwidth product (110MHz) and slew rate
(560V/µs), making the OPA4830 an ideal input buffer
stage to 3V and 5V CMOS analog-to-digital
converters (ADCs). Unlike other 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 OPA4830 is available in an industry-standard
quad pinout TSSOP-14 package.
