Maxim MAX11192 12位2MSPS SAR ADC解决方案
Maxim公司的MAX11192是同时取样2MSPS的双路SAR ADC,具有12位分辨率和差分输入,16引脚3mm x 2mm超细TDFN封装,提供极好的静态和动态性能,工作电压3.0V-5.25V,SNR大于73dB,THD典型值为-108dB,不丢失码的INL为±0.5LSB,主要用在编码器,解析器,LVDT,马达电流检测和PLC.本文介绍了MAX11192主要优势和特性,应用框图和应用电路,以及评估板MAX11192 EVK优势和特性,框图,电路图,材料清单和PCB设计图.
The MAX11192 is a dual-channel SAR ADC with simultaneoussampling at 2Msps, 12-bit resolution, and differentialinputs. Available in a tiny 16-pin, 3mm x 2mm ultra TDFNpackage, this ADC delivers excellent static and dynamicperformance while operating from a supply voltage overthe range of 3.0V to 5.25V. An integrated reference further reduces board area and component count.
The MAX11192 achieves 73dB of SNR (min), -108dBof THD (typ), and INL less than ±0.5LSB with no missingcodes. The SPI-compatible serial interface includesa separate data output for each channel. Specificationsapply over the extended industrial temperature range of-40 ℃ to +125 ℃ .
MAX11192主要优势和特性:
●● Tiny 16-Pin, 3mm x 2mm, Ultra TDFN Package
●● Up to 2Msps Throughput Rate
