Press Release Summary:
With sample rates up to 600 KSPS, 16-bit AD7981 PulSAR® A/D Converter is suited for wide bandwidth sonic and vibration measurement as well as low-power, lower-bandwidth pressure and temperature sensing. Device maximizes battery life in harsh environments by scaling power linearly with sample rate, using 4.65 mW at full speed of 600 KSPS and 70 µW at 10 KSPS. Housed in 10-lead MSOP package, Model AD7981 features typical performance of ±0.7 LSB INL and 91 dB SNR.
Original Press Release:
Analog Devices Introduces Industry's Fastest, Most Accurate and Lowest Power High-Temperature SAR A/D Converter
Specified to 175-degree Celsius operation, the AD7981 PulSAR® A/D converter targets high precision in harsh, high-temperature environments including downhole drilling, heavy industry and avionics.
NORWOOD, Mass.-- Analog Devices, Inc. (NASDAQ: ADI) today introduced the industry’s highest speed, high–temperature, 16-bit, A/D converter, which is more than twice as fast as currently available converters and provides error-free operation at temperatures of up to 175 degrees Celsius.
With sample rates up to 600-kSPS, the AD7981 PulSAR® A/D converter is ideally suited for applications including wide bandwidth sonic and vibration measurement as well as low power, lower-bandwidth pressure and temperature sensing. The AD7981 maximizes battery life in harsh environments by scaling power linearly with the sample rate, using only 4.65 mW at a full speed of 600 kSPS and 70 µW at 10 kSPS. The A/D converter features typical performance of +/-0.7-LSB INL and 91-dB SNR enabling a high dynamic range with better accuracy and precision. This combination addresses critical performance criteria for precision measurement applications in harsh, high-temperature environments such as down-hole oil and gas drilling, as well as industrial and avionics applications.
