Texas Instruments DRV134PASell Excess Inventory

General Description

The DRV134 and its companion DRV135 are precision differential output amplifiers designed to convert unbalanced input signals into balanced outputs. These devices integrate high-performance op amps with on-chip laser-trimmed precision resistors that ensure accurate gain and excellent common-mode rejection (CMR).

With a wide output voltage swing and high slew rate, the DRV134PA delivers superior AC performance, driving long cables and capacitive loads without distortion. When used with the INA134 or INA137 differential receivers, it forms a complete, low-noise signal chain for balanced audio transmission.

The DRV134PA comes in a 8-pin DIP package, ideal for through-hole assembly and prototyping environments. It operates across a wide temperature range from −40°C to +85°C and is fully specified for industrial and audio applications that demand precision and reliability.
