AD766716-Bit, 1 MSPS PulSAR®Unipolar ADC with Ref | Data Acquisition | 5 | Active | The AD7667 is a 16-bit, 1 MSPS, charge redistribution SAR analog-to-digital converter that operates from a single 5 V power supply. The part contains a high speed 16-bit sampling ADC, an internal conversion clock, internal reference, error correction circuits, and both serial and parallel system interface ports. It features a very high sampling rate mode (Warp), a fast mode (Normal) for asynchronous applications, and a reduced power mode (Impulse) for low power applications where power is scaled with the throughput. The AD7667 is hardware factory-calibrated and comprehensively tested to ensure ac parameters such as signal-to-noise ratio (SNR) and total harmonic distortion (THD) in addition to the more traditional dc parameters of gain, offset, and linearity. Operation is specified from –40°C to +85°C.PRODUCT HIGHLIGHTSFast Throughput.The AD7667 is a 1 MSPS, charge redistribution, 16-bit SAR ADC with internal error correction circuitry.Superior INL.The AD7667 has a maximum integral nonlinearity of 2.0 LSBs with no missing 16-bit codes.Internal Reference.The AD7667 has an internal reference with a typical temperature drift of 3 ppm/°C.Single-Supply Operation.The AD7667 operates from a single 5 V supply. In Impulse mode, its power dissipation decreases with throughput.Serial or Parallel Interface.Versatile parallel or 2-wire serial interface arrangement is compatible with both 3 V and 5 V logic.APPLICATIONSData AcquisitionInstrumentationDigital Signal ProcessingSpectrum AnalysisMedical InstrumentsBattery-Powered SystemsProcess Control |
AD7669LC2MOS Complete, 8-Bit Analog I/0 Dual DAC Output | Integrated Circuits (ICs) | 9 | Active | TheAD7569/ AD7669 is a complete, 8-bit, analog I/O system on a single monolithic chip. The AD7569 contains a high speed successive approximation ADC with 2 µs conversion time, a track/ hold with 200 kHz bandwidth, a DAC and an output buffer amplifier with 1 ms settling time. A temperature-compensated 1.25 V bandgap reference provides a precision reference voltage for the ADC and the DAC. The AD7669 is similar, but contains two DACs with output buffer amplifiers.A choice of analog input/output ranges is available. Using a supply voltage of +5 V, input and output ranges of zero to 1.25 V and zero to 2.5 volts may be programmed using the RANGE input pin. Using a ±5 V supply, bipolar ranges of ±1.25 V or ±2.5 V may be programmed.Digital interfacing is via an 8-bit I/O port and standard microprocessor control lines. Bus interface timing is extremely fast, allowing easy connection to all popular 8-bit microprocessors. A separate start convert line controls the track/hold and ADC to give precise control of the sampling period.The AD7569 / AD7669 is fabricated in Linear-Compatible CMOS (LC2MOS), an advanced, mixed technology process combining precision bipolar circuits with low power CMOS logic. The AD7569 is packaged in a 24-pin, 0.3" wide "skinny" DIP, a 24-terminal SOIC and 28-terminal PLCC and LCCC packages. The AD7669 is available in a 28-pin, 0.6" plastic DIP, 28-terminal SOIC and 28-terminal PLCC package. |
