OPA1671 - 12MHz, High cap drive, low-noise, rail-to-rail, audio operational amplifier

The OPA1671 is a wide bandwidth, low-noise, low-distortion, audio operational amplifierthat provides rail-to-rail input and output operation. The devices offers an excellent combinationof low voltage noise, current noise, and input capacitance, allowing it to deliver high performancein a wide array of audio and industrial applications. The unique internal topology of the OPA1671delivers very low distortion (–109 dB), while only consuming 940 µA of power supply current. Thewide bandwidth (12 MHz) and high slew rate (5 V/µs) of OPA1671 makes it an excellent choice forhigh gain audio and industrial signal conditioning. The OPA1671 is available in the SC-70 packagespecified over the extended industrial temperature range (–40°C to +125°C).
