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.
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.
About ADI’s High-Temperature Portfolio
The AD7981 adds to ADI’s portfolio of precision high-temperature
components, including the AD8229 ultra-low-noise instrumentation
amplifier; the ADR225 2.5-V band gap voltage reference; the AD8634
dual amplifier with rail-to-rail outputs and the ADXRS645 MEMS
(micro-electromechanical) gyroscope, all of which are specified to
operate at 175 degrees Celsius and higher. These components are
specifically manufactured for high temperature environments and are
production tested at high temperature to reduce risk and
development time for these demanding applications.
