INA2137UA/2K5

The INA137 and INA2137 are differential line receivers suitable for a wide range of audio and general - purpose applications. The INA137 and INA2137 were designed for enhanced ac performance. Very low distortion, low noise, and wide bandwidth provide superior performance in high quality audio applications. Laser - trimmed matched resistors provide optimum common - mode rejection (typically 90dB), especially when compared to circuits implemented with an op amp and discrete precision resistors. In addition, high slew rate (14V/µs) and fast settling time (3µs to 0.01%) ensure excellent dynamic performance. The INA137 and INA2137 have excellent distortion characteristics. THD + Noise is below 0.001% throughout the audio frequency range. Up to approximately 10kHz distortion is below the measurement limit of commonly used test equipment. Furthermore, distortion remains relatively flat over its wide output voltage swing range (approximately 1.7V from either supply). The INA137 and INA2137 are laser trimmed for low offset voltage and drift. Most applications require no external offset adjustment.
