OP162

超低噪声放大器的低功耗 Ultralow Noise Amplifier at Lower Power

Product Details

The single, OP262 dual, and OP462 quad rail-to-rail 15 MHz amplifiers feature the extra speed new designs require, with the benefits of precision and low power operation. With their incredibly low offset voltage of 45 µV typical and low noise, they are perfectly suited for precision filter applications and instrumentation. The low supply current of 500 µA typical is critical for portable or densely packed designs. In addition, the rail-to-rail output swing provides greater dynamic range and control than standard video amplifiers.

These products operate from single supplies as low as 2.7 V to dual supplies of ±6 V. The fast settling times and wide output swings recommend them for buffers to sampling A/D converters. The output drive of 30 mA sink and source is needed for many audio and display applications; more output current can be supplied for limited durations. The OPx62 family is specified over the extended industrial temperature range –40°C to +125°C. The single OP162 amplifiers are available in 8-lead SOIC package. The dual OP262 amplifiers are available in 8 lead SOIC and TSSOP packages. The quad OP462 amplifiers are available in 14-lead, narrow-body SOIC and TSSOP packages.
