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.
