ROHM Introduces High-Performance CMOS Op Amps for Diverse Applications

ROHM Unveils New Series of CMOS Operational Amplifiers

ROHM Co., Ltd., a leading manufacturer in the semiconductor space, has expanded its product offerings with a new line of high-performance CMOS operational amplifiers (op amps) known as the "TLRx728" and "BD728x" series. These new op amps are engineered to cater to a wide array of applications including those in automotive, industrial, and consumer electronics, addressing the growing demand for precision and efficiency in electronics design.

Meeting the Demand for Precision and Speed

As the complexity of automotive and industrial systems increases, there is a significant need for operational amplifiers that can deliver high accuracy while minimizing signal errors and delays. The TL7RX728 and BD728x series have been designed with key performance metrics in mind, including low input offset voltage, low noise, and a high slew rate. The TLRx728 boasts an input offset voltage of approximately 150 microvolts, while the BD728x maintains an input offset voltage of about 1.6 millivolts. Both series maintain a noise voltage density of 12 nanovolts per square root hertz at 1kHz along with a slew rate of 10 volts per microsecond, making them ideal for high-precision applications.

These performance characteristics allow the op amps to excel in applications that require sensor signal processing, current detection, motor driver control, and power supply monitoring. By balancing versatility with performance, ROHM ensures that these op amps can accommodate a range of applications rather than limiting their use to specific scenarios.

Versatility in Design

A standout feature of the TL7RX728 and BD728x series is their rail-to-rail input/output capability. This design enhances the use of the entire power supply voltage range, ensuring a wide dynamic range, which makes these op amps even more suitable for various applications. The product lineup includes configurations with 1, 2, or 4 channels and is available in various package types, allowing engineers to select the most appropriate option based on their design requirements and space constraints.

ROHM’s commitment to enhancing design flexibility is exemplified by the diverse range of available packages, enabling optimal selection for application needs and board specifications.

Availability and Pricing

The new product series is being offered globally, excluding certain part numbers. The sample pricing is competitive, with the 1-channel version priced at $2.00, the 2-channel at $2.80, and the 4-channel version at $4.00, all excluding tax. Customers can conveniently purchase these devices online through major distributors such as DigiKey, Mouser, and Farnell.

Conclusion

The introduction of the TL7RX728 and BD728x operational amplifiers solidifies ROHM's position as a leader in the semiconductor industry, responding effectively to the increasing demand for high-performance electronic components in a wide range of applications. With these advanced op amps, engineers and designers can achieve higher efficiency, better precision, and enhanced performance in their electronic systems.
