Connection Diagram

Figure 4 shows a connection diagram for the

CS3302 amplifier when used with the CS5372 dual

∆Σ modulator, the CS4373A test DAC and the

CS5376A digital filter. The diagram shows differ-

ential sensors, a test DAC, and analog outputs with

anti-alias capacitors; power supply connections in-

cluding recommended bypassing; and digital con-

trol connections back to the CS5376A GPIO pins.
