The DRV134 and DRV135 are differential output amplifiers that convert a single-ended input to a balanced output pair. They consist of high-performance op amps with on-chip precision resistors, and are fully specified for high-performance audio applications with excellent AC performance including low distortion and high slew rate. They can easily drive large capacitive loads associated with long audio cables. When used in combination with the INA134 or INA137 differential receivers, they provide a complete solution for transmitting analog audio signals without degradation.
The DRV134 and DRV135 are differential‑output audio line‑driver integrated circuits that convert a single‑ended input to a balanced output pair. They incorporate high‑performance op‑amps with laser‑trimmed on‑chip resistors, delivering ultra‑low distortion (0.0005% at 1 kHz) and a high slew rate of 15 V/µs. The devices support a wide supply range of ±4.5 V to ±18 V and provide up to +27 dBu output level.
Both parts are offered in multiple packages: the DRV134 in 8‑pin DIP and SOL‑16 surface‑mount packages, and the DRV135 in a compact SO‑8 package. Typical applications include audio mixing consoles, distribution amplifiers, graphic/parametric equalizers, dynamic‑range processors, digital‑effects processors, telecom systems, hi‑fi equipment and industrial instrumentation.
