Description
General part information
AD7621 Series
The AD7621 is a 16-bit, 3 MSPS, charge redistribution SAR, fully differential analog-to-digital converter that operates from a single 2.5 V power supply. The part contains a high-speed 16-bit sampling ADC, an internal conversion clock, an internal reference buffer, error correction circuits, and both serial and parallel system interface ports. It features a very high sampling rate mode (Wideband Warp) for undersampling applications and, for asynchronous conversion rate applications, a fast mode (Normal) and, for low power applications, a reduced power mode (Impulse) where the power is scaled with the throughput. Operation is specified from −40°C to +85°C.It is available in a 48-lead LQFP or a 48-lead LFCSP with operation specified from –40°C to +85°C.PRODUCT HIGHLIGHTSFast Throughput.The AD7621 is a 3 MSPS, charge redistribution, 16-bit SAR ADC.Superior Linearity.The AD7621 has no missing 16-bit code.Internal Reference.The AD7621 has a 2.048 V internal reference with a typical drift of ±7 ppm/°C.Single-Supply Operation.The AD7621 operates from a 2.5 V single supply and typically dissipates 65 mW. In impulse mode, its power dissipation decreases with the throughput.Serial or Parallel Interface.Versatile parallel (16- or 8-bit bus) or 2-wire serial interface arrangement compatible with 2.5 V, 3.3 V, or 5 V logic.APPLICATIONSMedical instrumentsHigh speed data acquisitionDigital signal processingCommunicationsInstrumentationSpectrum analysisATE
