1.1
The CDB5560 evaluation board has both analog and digital circuit sections. The analog section consists
of the CS5560 ADC, two analog input signal buffers, controlled through a multiplexer, that condition the
signals into the ADC, and a precision 4.096 V reference. The digital section consists of board operation
configuration control signals, reset circuitry, an SPI™ serial port, a jumper connection for initiating ADC
calibration, and an EEPROM for evaluation board identification.
The evaluation board operates from +2.5V, -2.5V, +3.3V and communicates through an SPI™ serial port.
Figure 1 illustrates the CDB5560 block diagram.
