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

The on-chip resistors are laser-trimmed for accurate gain and optimum output common-mode rejection. Wide output voltage swing and high output drive capability allow use in a wide variety of demanding applications. They easily drive the large capacitive loads associated with long audio cables. Used in combination with the INA134 or INA137 differential receivers, they offer 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 comes in a space-saving SO-8 surface-mount package. Both are specified for operation over the extended industrial temperature range, –40°C to +85°C and operate from –55°C to +125°C.
