1. The diode-connected configuration provides better settling time. The transistor-connected configuration provides better series resistance cancellation. TI recommends a MMBT3904 or MMBT3906 transistor with an η-factor of 1.008.
2. RS (optional) is < 1 kΩ in most applications. RS is the combined series resistance connected externally to the D+, D– pins. RS selection depends on the application.
3. CDIFF (optional) is < 1000 pF in most applications. CDIFF selection depends on the application; see Figure 7.
4. Unused diode channels must be tied to D– .
