Fast Precision Solutions

Fast precision signal chains address applications that demand both high precision and speed. These signal chains offer the flexibility needed to optimize them for either measurement or drive solutions. They combine fast sampling rates with high resolution that support bandwidths up to 1 MHz, with no compromise between DC and AC precision and accuracy. Analog Devices’ catalog of fast precision components enables full signal chain solutions that meet critical specifications for DC linearity, settling time, latency, total harmonic distortion (THD), and signal-to-noise ratios (SNR) exceeding 90 dB.

Values and Benefits

Fast precision signal chains offer curated solutions that combine precision amplifiers, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), circuit protection, voltage references, and isolation components, allowing system designers to explore solutions that can be optimized for both precision and speed.

These solutions offer the flexibility to modify parameters such as resolution, gain, and bandwidth to meet system requirements. They cover applications such as hardware-in-the-loop (HIL), nondestructive test, scanning electron microscopes (SEM), and flow cytometry, where speeds above 100 kHz and SNR >85 dB are required.
