OPA1671IDCKT Product Details

The OPA1671IDCKT is a wide-bandwidth, low-noise, low-distortion, audio operational amplifierthat provides rail-to-rail input and output operation. This device offers an excellent combinationof low voltage noise, current noise, and input capacitance, allowing the device to deliver highperformance in a wide array of audio and industrial applications. The unique internal topology ofthe OPA1671IDCKT delivers very low distortion (–109 dB), while only consuming 940 μA of power supplycurrent. The wide bandwidth (13 MHz) and high slew rate (5 V/μs) of OPA1671IDCKT makes this device anexcellent choice for high gain audio and industrial signal conditioning.

The OPA1671IDCKT is available in the SC-70 and SOT-23 packages and is specified over theindustrial temperature range (–40°C to +125°C).
