OPA2830数据手册TI中文资料规格书

描述 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.
