Description
General part information
AD7674 Series
The AD7674 is an 18-bit, 800 kSPS, charge redistribution, successive approximation register (SAR) fully differential analog-to-digital converter (ADC) that operates on a single 5 V power supply. The device contains a high speed, 18-bit sampling ADC, an internal conversion clock, an internal reference buffer, error correction circuits, and both serial and parallel system interface ports.The device is available in a 48-lead LQFP or a 48-lead LFCSP with operation specified from −40°C to +85°C.Product HighlightsHigh Resolution, Fast Throughput. The AD7674 is an 800 kSPS, charge redistribution, 18-bit, SAR ADC (no latency).Excellent Accuracy. The AD7674 has a maximum integral nonlinearity of 2.5 LSB with no missing 18-bit codes.Serial or Parallel Interface. Versatile parallel (18-, 16- or 8-bit bus) or 3-wire serial interface arrangement compatible with both 3 V and 5 V logic.ApplicationsCT scannersHigh dynamic data acquisitionGeophone and hydrophone sensors∑-∆ replacement (low power, multichannel)InstrumentationSpectrum analysisMedical instruments
