2.3 EVM Theory and Operation
The following single channel schematic is representative of the TLA431EVM with each passive bank selection.
Figure 2-1 Base Shunt Reference
SchematicThe TLA431EVM is designed to allow users to setup the configuration shown in Figure 2-1 with multiple options for each passive component and open footprints to test multiple use-cases. Table 2-3 shows a mapping of EVM components to board base components.
Table 2-3 EVM Component Mapping
| Base Component | EVM Components |
|---|---|
| Rsup | R6 |
| R1 | R2 – R5, R1_user |
| R2 | R7, R2_user |
| CL | C_user |
As shown in Figure 3-1, the EVM is designed to allow users to visually map out each jumper connection to the respective passive component by the labeling of the configuration value next to J1.
