The MAX14001/14002 evaluation system (EV system) provides the hardware and software necessary to evaluate the MAX14001 and MAX14002 isolated, single-channel, analog-to-digital converters (ADCs) with programmable voltage comparators and inrush current control optimized for configurable binary input applications. The MAX14001/ MAX14002 EV kit has Pmod™ compatible connectors for SPI communication. The EV system includes the USB2PMB2 adapter board that receives commands from a PC through the USB cable to create an SPI interface for communication between the software and the MAX14001/MAX14002 on the EV kit.
The EV system includes a graphical user interface (GUI) that provides communication between the target device and the PC. The MAX14001/MAX14002 EV kit has two MAX14001/MAX14002 devices (U1 and U2) that can operate in multiple modes, as shown in Figure 1:
Single Channel mode: The USB2PMB2 adapter connects to connector PMOD1 or PMOD2 on the EV kit, depending on which channel is preferred, allowing differently configured analog inputs with signal conditioning circuitry.
Daisy-Chain mode: The USB2PMB2 adapter connects to connector PMOD1, and DOUT from U1 connects to DIN of U2. Both U1 and U2 are controlled from a single SPI interface.
Dual Channel mode: The USB2PMB2 adapter connects to connector PMOD1 and uses two chipselect signals (CS1 and CS2) to control each chip through a single connector/GUI interface.
