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.
