Dual audio differential line receiver, INA2134UA, Texas Instruments
The INA2134UA is differential line receiver consisting of high performance op amp with on-chip precision resistor. It is fully specified for high performance audio application and has excellent ac specification, including low distortion (0.0005% at 1kHz) and high slew rate (14V/µs), assuring good dynamic response. In addition, wide output voltage swing and high output drive capability allows use in a wide variety of demanding application. The dual version features completely independent circuitry for lowest crosstalk and freedom from interaction, even when overdriven or overloaded. The INA2134UA on-chip resistor is laser trimmed for accurate gain and optimum common-mode rejection. Furthermore, excellent TCR tracking of the resistor maintains gain accuracy and common-mode rejection over temperature. Operation is guaranteed from ±4V to ±18V (8V to 36V total supply).
