It contains a precision, low power, 24-bit sigma-delta (Σ-Δ) ADC; an on-chip, low noise programmable gain amplifier (PGA); and an on-chip oscillator. Consuming only 330 μA, the AD7780 is particularly suitable for portable or battery-operated products where very low power is required. The AD7780 also has a power-down mode that allows the user to switch off the power to the bridge sensor and power down the AD7780 when not converting, thus increasing the battery life of the product. For ease of use, all the features of the AD7780 are controlled by dedicated pins. Each time a data read occurs, eight status bits are appended to the 24-bit conversion. These status bits contain a pattern sequence that can be used to confirm the validity of the serial transfer. 有关AD7780BRZ代理、AD7780BRZ中文资料、AD7780BRZ应用电路、AD7780BRZ引脚功能、AD7780BRZ原理图、AD7780BRZ型号封装、AD7780BRZ PDF、AD7780BRZ价格、AD7780BRZ厂家图片、AD7780BRZ现货供应信息，欢迎来电咨询!直线：13316887805 QQ：2501633055 范小姐
