The device has the advantage of excellent anti-RF interference capability, making it very suitable for use in poor 24-bit A/D measurement application environments. The device includes a fully integrated LDO whose output can be used as a power supply for external sensors, such as those for weight, pressure and temperature measurements.

Holtek also provides reference designs, such as weighing modules, pressure modules, temperature modules and so on, which can help designers reduce the product development cycle time. An additional advantage of the device is its 10-pin SOP small package, which is suitable for use in various sensor signal processing applications. When aimed at diverse applications with their different MCU requirements, the flexibility and wide range of functions offered by this device makes it an excellent choice.

The device includes fully integrated LDO, PGA and a 24-bit Delta Sigma A/D Converter. With this high level of functional integration, the required number of external components is greatly reduced which will result in reduced manufacturing costs and improved productivity. The device includes 2K words of Flash Program Memory, 128 bytes of Data Memory, 32 bytes of True Data EEPROM and Timer Modules. The device also provides multiple serial interfaces, including SPI, I2C and UART.

With regard to packaging, the device is supplied in a 10-pin SOP package type.
