2. Specifications guaranteed by design, characterization, and/or test.
3. Analog signals are relative to VA- and digital signals to DGND unless otherwise noted.
4. The minimum FSCR is limited by the maximum allowed gain register value.
5. Effective Input Impedance (EII) varies with clock frequency (DCLK) and Input Capacitance (IC)
EII = 1/(IC*DCLK/4)
