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 1kHz) and high slew rate (15V/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.
