The AD7679ASTZ is an 18-bit SAR ADC from Analog Devices featuring a successive approximation register architecture with no pipeline delay. It achieves a throughput of 570 kSPS with a typical power dissipation of 76 mW at 500 kSPS. The device accepts a differential input voltage range of ±VREF (up to 5 V) and provides an integral nonlinearity of ±2.5 LSB maximum. Typical dynamic range is 103 dB, and signal-to-noise and distortion (SINAD) is 100 dB at 2 kHz input frequency.
Interface options include parallel (18-, 16-, or 8-bit bus) and serial interfaces compatible with SPI, QSPI, MICROWIRE, and DSP protocols. An on-board reference buffer simplifies external reference design. The ADC operates from a single 5 V analog supply and is specified over the -40°C to 85°C temperature range.
The AD7679ASTZ is housed in a 48-lead LQFP package (7x7 mm) and is surface mount compatible. It is suitable for applications such as CT scanners, high dynamic data acquisition, geophone and hydrophone sensors, sigma-delta replacement in low-power multichannel systems, instrumentation, spectrum analysis, and medical instruments.
