General Description

The DRV135 and its dual version DRV134 are precision differential output amplifiers that convert unbalanced signals into balanced output pairs. These integrated audio drivers use high-performance op amps with laser-trimmed on-chip precision resistors for accurate gain and optimized common-mode rejection.

Thanks to their wide voltage swing and high output drive capability, the DRV135 family can easily drive large capacitive loads such as long audio cables. When paired with devices like the INA134 or INA137, they provide a complete, distortion-free solution for transmitting analog audio signals over long distances.

The DRV135UA/2K5 version is supplied in a compact SO-8 surface-mount package, qualified for industrial-grade operation over an extended temperature range of −40°C to +85°C. It ensures stable performance even in challenging environments, making it ideal for professional audio and industrial instrumentation systems.
