      The OPA1671 is a wide-bandwidth, low-noise, low-distortion, audio operational amplifier that provides rail-to-rail input and output operation. This device offers an excellent combination of low voltage noise, current noise, and input capacitance, allowing the device to deliver high performance in a wide array of audio and industrial applications. The unique internal topology of the OPA1671 delivers very low distortion (–109 dB), while only consuming 940 µA of power supply current. The wide bandwidth (13 MHz) and high slew rate (5 V/µs) of OPA1671 makes this device an excellent choice for high gain audio and industrial signal conditioning.

      The OPA1671 is available in the SC-70 and SOT-23 packages and is specified over the industrial temperature range (–40°C to +125°C).
