Ultra Precision Solutions

Ultra-precision signal chains address applications that demand the highest precision and stability. These signal chains offer the flexibility needed to optimize them for requirements that address both measurement and drive solutions. They combine high resolution data converters, ultra-stable voltage references, and low noise, low drift amplifiers into signal chains that deliver the ultimate in both DC and AC precision and accuracy. Analog Devices’ catalog of ultra-precision components enables full signal chain solutions that meet demanding specifications for low drift over temperature, DC linearity and error, settling time, total harmonic distortion (THD), and signal-to-noise ratios (SNR) exceeding 90 dB.
