TI ADS131E08 24位低功耗模拟前端(AFE)解决方案
TI 公司的ADS131E08是24位低功耗模拟前端(AFE),内置可编增益放大器(PGA),基准电源和振荡器,具有工业电源监视,控制和保护等功能.ADS131E0x有八个差分电流和电压输入,1 kSPS时的动态范围118dB,串扰-110dB,50Hz和60Hz的THD为-90dB,主要用在能量计量,电源监视,控制和保护等.本文介绍了ADS131E0x主要特性,方框图,典型应用电路图,以及功率监视系统框架图,ADS131E08EVM-PDK评估板主要特性,电路图,材料清单和PCB元件布局图.
The ADS131E0x are a family of multichannel, simultaneous sampling, 24- and 16-bit, delta-sigma (ΔΣ), analog-to-digital converters (ADCs) with a built-in programmable gain amplifier (PGA), internal reference, and an onboard oscillator.
The ADS131E0x incorporate features commonly required in industrial power monitoring, control, and protection applications. The ADS131E0x inputs can be independently and directly interfaced with a resistor-divider network or a transformer to measure voltage. The inputs can also be interfaced to a current transformer or Rogowski coil to measure current. With high integration levels and exceptional performance, the ADS131E0x family enables the creation of scalable industrial power systems at significantly reduced size, power, and low overall cost.
