The Reimagined Sigma-Delta
A REVOLUTIONARY LEAP FORWARD IN SENSING
Direct to Digital Sigma-Delta Analog Front Ends (AFE’s)
SigmaSense AFE’s shift impedance sensing into the digital domain by uniquely converting minute changes in current to digital data. This capability delivers unprecedented improvements in sensitivity and Signal to Noise Ratio (SNR). SigmaSense’s proprietary sigma-delta drive-sense circuits offer continuous operation, ultra-low drive voltages, and self-excitation / self-biasing that moves digital sensing much closer to the analog event horizon.
