Data Sheet
- Detailed Description
Additionally the bandgap voltage can be adjusted about ±100mV by forcing a voltage to the REFADJ pin. The REFADJ
input impedance is typically 17k
Ω
.
Figure 32
shows a possible arrangement.
Figure 32. Reference Adjust Circuit
External Reference
An external reference can be connected directly at pin REF. To use the external reference, the internal buffer must be
disabled by connecting pin REFADJ to pin VDD. The input resistance is typically 15k
Ω
.
During conversion, an external reference at pin REF must deliver up to 350μA DC load current and have 10
Ω
or less
output impedance. If the reference has a higher output impedance or is noisy, bypass it with a 4.7μF capacitor placed
as close to pin REF as possible.
Note:
Using the REFADJ input makes buffering the external reference unnecessary.
