DESCRIPTION
The DRV134 and DRV135 are differential output ampli-
fiers 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 resis-
tors. They are fully specified for high performance audio
applications and have excellent ac specifications, in-
cluding 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 sur-
face-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.
