A. 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.
B. 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.
C. CDIFF (optional) is
< 1000 pF in most applications. CDIFF selection depends on the
application; see Figure 6-5.
D. Unused diode channels must be tied
to D– as shown for D5+.
