Texas Instruments DRV134UA/1KSell Excess Inventory

General Description

The DRV134 and its single-channel counterpart DRV135 are precision differential output amplifiers that convert single-ended inputs to balanced outputs. These devices feature high-performance operational amplifiers combined with laser-trimmed, on-chip precision resistors to provide accurate gain and optimized common-mode rejection (CMR).

With wide output voltage swing and high output drive capability, the DRV134UA/1K can easily handle large capacitive loads found in long audio cable runs or complex signal routing systems. When used in combination with INA134 or INA137 line receivers, the DRV134 forms a complete professional-grade audio interface with minimal distortion and superior noise immunity.

The DRV134UA/1K variant is housed in a space-saving SOIC-8 surface-mount package, offering excellent thermal performance and mechanical stability. It operates over a wide temperature range of −40°C to +85°C, making it ideal for use in both commercial and industrial environments.

FAQs

What is the DRV134 used for?

It is a precision audio line driver that converts single-ended signals into balanced outputs, used to minimize noise in long audio cable applications.

What is the difference between DRV134 and DRV135?

The DRV134 provides two balanced outputs (dual channel) in a 16-pin package, while the DRV135 is a single-channel version in an 8-pin SOIC package.

Can the DRV134 be used as a replacement for SSM2142?

Yes. The DRV134 is a direct, improved replacement for the SSM2142, offering lower distortion, higher slew rate, and better reliability.
