ADC12EU050 - 超低功耗、八通道、12 位、45 MSPS Δ-Σ 模数转换器 - 高速ADC(>10MSPS) - 模数转换器 - TI公司（Texas Instruments，德州仪器）
The ADC12EU050 is a 12-bit, ultra-low power, octal A/D converter for use in high performance analog to digital applications. The ADC12EU050 uses an innovative continuous time sigma delta architecture offering ultra low power consumption and an alias free sample bandwidth up to 22.5MHz. The input stage of each channel features a proprietary system to ensure instantaneous recovery from overdrive. Instant overload recovery (IOR) with no memory effect ensures the elimination of phase errors resulting from out of range input signals. The ADC12EU050 reduces interconnection complexity by using programmable serialized outputs which offer the industry standard LVDS and SLVS modes. Power consumption of only 46mW per channel @ 45MSPS gives a total chip power consumption of 364mW. The ADC12EU050 can operate entirely from a 1.2V supply, although a separate output driver supply of up to 1.8V can be used. The device operates from 0 to +70 °C and is supplied in a 10 x 10 mm2, 68-pin VQFN package.
