Connection Diagram

Figure 4 shows a connection diagram for the

CS3301 amplifier when used with the CS5372 dual

∆Σ modulator and CS5376A digital filter. The dia-

gram shows differential sensors, a test DAC, and

analog outputs with anti-alias capacitors; power

supply connections including recommended by-

passing; and digital control connections back to the

CS5376A GPIO pins.
