- Package: Pb-free SOT23
The OPA830 is a low-power, single-supply, wideband, voltage-feedback amplifier designed to operate on a single 3V or 5V supply. The device also supports operation on ±5V or +10V supplies. The input range extends below the negative supply and to within 1.7V of the positive supply. Using complementary common-emitter outputs provides an output swing to within 25mV of either supply while driving 150Ω. High output drive current (±80mA) and low differential gain and phase errors also make this device an excellent choice for single-supply consumer video products.
Low distortion operation is provided by the high gain bandwidth product (110MHz) and slew rate (550V/µs), making the OPA830 an excellent input buffer stage to 3V and 5V CMOS ADCs. Unlike other low-power, single-supply amplifiers, distortion performance improves as the signal swing decreases. A low 9.2nV/√Hz input voltage noise supports wide dynamic range operation.
The OPA830 is available in an industry-standard SO-8 package, and in an ultra-small SOT23-5 package. For fixed-gain line driver applications, consider the OPA832.
