series introduction
The **HCPL-788J Series** is a family of high-performance, optically isolated sigma-delta modulators designed for precision current sensing and voltage measurement applications. These devices are engineered to provide exceptional accuracy, reliability, and noise immunity, making them ideal for use in demanding industrial and automotive environments. The HCPL-788J Series combines advanced optical isolation technology with a sigma-delta modulation architecture to deliver high-resolution analog-to-digital conversion, ensuring precise signal acquisition and transmission across isolation barriers.
One of the key features of the HCPL-788J Series is its high common-mode transient immunity (CMTI), which ensures reliable operation in the presence of fast voltage transients and noise. This makes the series particularly well-suited for applications such as motor control, power inverters, and battery management systems, where electrical noise and transient voltages are common. The devices also feature a wide operating temperature range, typically from -40°C to +105°C, ensuring consistent performance in harsh environments. Additionally, the HCPL-788J Series offers low offset and gain drift over temperature, which enhances measurement accuracy and stability over time.
The design of the HCPL-788J Series emphasizes compactness and ease of integration. The devices are housed in small, surface-mount packages, making them suitable for space-constrained applications. The optical isolation technology eliminates the need for external isolation components, simplifying system design and reducing overall board space. Furthermore, the series supports a wide input voltage range and provides a digital output interface that is compatible with most microcontrollers and digital signal processors (DSPs), enabling seamless integration into modern control systems.
Typical applications for the HCPL-788J Series include current sensing in motor drives, solar inverters, and uninterruptible power supplies (UPS), as well as voltage monitoring in electric vehicles (EVs) and industrial automation systems. The series is also widely used in energy metering and power quality monitoring, where high accuracy and isolation are critical. With its robust design, high performance, and versatility, the HCPL-788J Series is a trusted solution for engineers seeking reliable and precise signal isolation in a wide range of industrial and automotive applications.
