Product Description
Product Overview
The ADS1194/6/8 family offers a highly integrated, low-power, 8-channel, 16-bit analog front-end for biopotential measurements. These devices enable the creation of scalable medical instrumentation systems with reduced size, power, and cost. They feature flexible input multiplexers, on-chip test signals, temperature and lead-off detection, and integrated amplifiers for Wilson Center Terminal (WCT) and Goldberger terminals (GCT) generation. Multiple devices can be cascaded for high channel count systems.
