1 Typical values measured at 25°C, not subject to production test.
2 Data gathered using the 2 kHz packet/frame rate is measured over 0.5 seconds. The ADAS1000 internal programmable low-pass filter is configured for either 40 Hz or
150 Hz bandwidth. The data is gathered and post processed using a digital filter of either 0.05 Hz or 0.5 Hz to provide data over noted frequency bands.

3 Analog lead mode as shown in Figure 58.
4 Single-ended input electrode mode as shown in Figure 61. Electrode mode refers to common electrode A, common electrode B, and single-ended input electrode
configurations. See Electrode/Lead Formation and Input Stage Configuration section.
5 Digital lead mode as shown in Figure 59.
6 Digital lead mode is available in 2 kHz and 16 kHz data rates.
