en.Wedoany.com Reported - Japanese semiconductor manufacturer ROHM Co., Ltd. has recently launched two new series of CMOS operational amplifiers, namely the TLRx728 and BD728x, designed for automotive, industrial, and consumer electronic systems. This expansion of the product line provides users with more options.
As industrial automation and in-vehicle electronic systems become more complex, the precise amplification of sensor output signals is key to reducing errors and delays. The operational amplifiers released by ROHM achieve an excellent balance between input offset voltage, noise suppression, and slew rate. Among them, the TLRx728 series boasts a typical input offset voltage of only 150 microvolts ($\mu\text{V}$), demonstrating extremely high precision detection capability; while the BD728x series offers a typical offset voltage of 1.6 millivolts ($\text{mV}$). Both series feature a low noise voltage density of $12\text{nV}/\sqrt{\text{Hz}}$ (at 1kHz) and a high slew rate of $10\text{V}/\mu\text{s}$, ensuring real-time and pure signal processing.
To support a wide dynamic range, the series adopts a rail-to-rail input and output design, allowing full utilization of the signal swing across the entire power supply voltage range. The products are available in various configurations such as 1-channel, 2-channel, and 4-channel, and cover multiple package specifications to fit different space requirements ranging from miniature wearable devices to large industrial control boards. These characteristics make them ideal core components for sensor signal processing, current detection, motor drive control, and power supply monitoring systems.
Currently, except for a few specific models, the new products are available for immediate shipment and can be purchased through online distributors such as DigiKey, Mouser, and Farnell. Sample reference prices are $2.00 for the 1-channel version, $2.80 for the 2-channel version, and $4.00 for the 4-channel version (all excluding tax). ROHM stated that this series of versatile and high-performance operational amplifiers will provide more competitive analog technology support for precision electronic designs in China and globally.
