DESCRIPTION

The INA2134 is a differential line receiver consisting of high performance op amps with onchip precision

resistors. The device is fully specified for high performance audio applications and has excellent ac

specifications, including low distortion (0.0005% at 1 kHz) and high slew rate (14 V/ms), assuring good dynamic

response. In addition, wide output voltage swing and high output drive capability allow use in a wide variety of

demanding applications. The dual version features completely independent circuitry for lowest crosstalk and

freedom from interaction, even when overdriven or overloaded.

The INA2134 on-chip resistors are laser trimmed for accurate gain and optimum common-mode rejection.

Furthermore, excellent TCR tracking of the resistors maintains gain accuracy and common-mode rejection over

temperature. Operation is guaranteed from ±4 V to ±18 V (8-V to 36-V total supply).

The INA2134 comes in a 14-pin SOIC surface-mount package and is specified for operation over the military

temperature range, –55°C to 125°C.
