KI-Übersetzung

The ADS1194/6/8 are a series of multichannel, simultaneous-sampling, 16-bit, ΔΣ ADCs with built-in PGA, internal reference, and on-chip oscillator. With high integration and outstanding performance, the ADS1194/6/8 family can significantly reduce size, power consumption, and overall cost to create scalable medical instrumentation systems. Each channel of the ADS1194/6/8 features a flexible input multiplexer that can be independently connected to internally generated signals for testing, temperature measurement, and lead-off detection. In addition, any input channel configuration can be selected to derive the right leg drive (RLD) output signal. With data rates up to 8kSPS, the ADS1194/6/8 enables software-based pace detection. Lead-off detection can be implemented internally using pull-up/pull-down resistors or excitation current sink/source. Three integrated amplifiers generate the Wilson Central Terminal (WCT) and Goldberger Central Terminal (GCT) required for standard 12-lead medical ECG. Multiple ADS1194/6/8 devices can be daisy-chained in high-channel-count systems. Package options include an 8mm×8mm, 64-ball BGA and TQFP-64. Both packages support an operating temperature range of 0°C to +70°C.
