AD7626
16位， 10 MSPS ， PulSAR系列ADC差分 16-Bit, 10 MSPS, PulSAR Differential ADC
Product Details
The is a 16-bit, 10 MSPS, charge redistribution successive approximation register SAR based architecture analog-to-digital converter ADC. SAR architecture allows unmatched performance both in noise 91.5 dB SNR and in linearity ±0.45 LSB INL. The AD7626 contains a high speed, 16-bit sampling ADC, an internal conversion clock, and an internal buffered reference. On the CNV edge, it samples the voltage difference between the IN+ and IN− pins. The voltages on these pins swing in opposite phase between 0 V and REF. The 4.096 V reference voltage, REF, can be generated internally or applied externally.
All converted results are available on a single low voltage differential signaling LVDS self clocked or echoed clock serial interface, reducing external hardware connections.
The AD7626 is housed in a 32-lead, 5 mm × 5 mm LFCSP with operation specified from −40°C to +85°C.
