AD7625

16位， 6MSPS的PulSAR差分ADC 16-Bit, 6MSPS PulSAR Differential ADC

Product Details

The is a 16-bit, 6 MSPS, charge redistribution successive approximation register SAR based architecture analog-to-digital converter ADC. SAR architecture allows unmatched perfor-mance both in noise 93 dB SNR and in linearity 1 LSB. The AD7625 contains a high speed, 16-bit sampling ADC, an internal conversion clock, and an internal buffered reference. On the CNV± rising 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 LVDS self-clocked or echoed-clock serial interface, reducing external hardware connections.

The AD7625 is housed in a 32-lead, 5 mm × 5 mm LFCSP with operation specified from −40°C to +85°C.
