3 Description
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.
