DRV134UA is a low-distortion single-ended-to-balanced audio line driver for professional long-distance analog audio balanced transmission

The DRV134UA is a high-performance balanced audio differential line driver designed for professional long-distance analog audio balanced transmission. This differential output amplifier converts single-ended input signals to balanced differential output pairs.

Featuring high-speed operational amplifiers and on-chip laser-trimmed precision resistors, the DRV134UA delivers exceptional performance with low differential-mode output impedance (50Ω), high common-mode output impedance (1.6kΩ), ultra-low distortion, high slew rate, wide output swing, and robust capacitive load driving capability.

This device serves as an improved direct replacement for SSM2142, available in SOIC-16 surface-mount package with an operating temperature range of −40°C to +85°C.
