DRV135 is an audio balanced line driver available in SOIC-8

The DRV134 and DRV135 are differential output amplifiers that convert a single-ended input into a balanced output pair. These ADS5272IPFPT balanced audio drivers consist of high performance op amps with on-chip precision resistors. They are fully suited for high performance audio applications and feature excellent AC specifications including low distortion (0.0005% at 1 kHz) and high slew rate (15 V/μs).

On-chip resistors are laser trimmed for accurate gain and optimal output common-mode rejection. Wide output voltage swing and high output drive capability allow use in a variety of demanding applications. They can easily drive the large capacitive loads associated with long audio cables. Used in conjunction with the INA134 or INA137 differential receivers, they provide a complete solution for transmitting analog audio signals without degradation.

The DRV134 is available in 8-pin DIP and SOL-16 surface mount packages. The DRV135 is available in a space saving SO-8 surface mount package. Both are specified for operation over the extended industrial temperature range of –40°C to +85°C, and operation over the range of –55°C to +125°C.
