AD7671ASTZ Product Details

The AD7671ASTZ is a 16-bit, 1 MSPS, charge redistribution SAR, analog-to-digital converter that operates from a single 5 V power supply. It contains a high speed 16-bit sampling ADC, a resistor input scaler that allows various input ranges, an internal conversion clock, error correction circuits, and both serial and parallel system interface ports.

The AD7671ASTZ is hardware factory-calibrated and is comprehensively tested to ensure such ac parameters as signal-to-noise ratio (SNR) and total harmonic distortion (THD), in addition to the more traditional dc parameters of gain, offset, and linearity. 

It features a very high sampling rate mode (Warp), a fast mode (Normal) for asynchronous conversion rate applications, and, for low power applications, a reduced power mode (Impulse) where the power is scaled with the throughput. 

It is fabricated using Analog Devices’ high performance, 0.6 micron CMOS process and is available in a 48-lead LQFP and a tiny 48-lead LFCSP, with operation specified from –40°C to +85°C. 

Product Highlights

  • Fast ThroughputThe AD7671ASTZ is a very high speed (1 MSPS in Warp Mode and 800 kSPS in Normal Mode), charge redistribution, 16-bit SAR ADC.

  • Single-Supply OperationThe AD7671ASTZ operates from a single 5 V supply, dissipates only 112 mW typical, even lower when a reduced throughput is used with the reduced power mode (Impulse) and a powerdown mode.

  • Superior INLThe AD7671ASTZ has a maximum integral nonlinearity of 2.5 LSB with no missing 16-bit code.

  • Serial or Parallel InterfaceVersatile parallel (8 bits or 16 bits) or 2-wire serial interface arrangement compatible with both 3 V or 5 V logic.
