ROHM Semiconductor has announced the addition of two new CMOS operational amplifier (op amp) series, the TLRx728 and BD728x, to its lineup. These high-performance op amps feature low input offset voltage, low noise, and high slew rate, making them suitable for a wide range of precision applications in automotive, industrial, and consumer electronics.

Why it matters

As automotive and industrial systems become more sophisticated, there is growing demand for high-accuracy op amps that can minimize signal error and delay. ROHM's new op amp series are designed to meet these requirements, offering a well-balanced set of key characteristics to enable precise signal processing and control in a variety of applications.

The details

The TLRx728 series features an input offset voltage of 150 μV (typ.), while the BD728x series offers 1.6 mV (typ.). Both series have a noise voltage density of 12 nV/√Hz at 1kHz and a slew rate of 10 V/μs. These specifications make the op amps suitable for sensor signal processing, current detection circuits, motor driver control, and power supply monitoring systems. The op amps also feature rail-to-rail input/output capability for maximum utilization of the power supply voltage range.
