SETTING UP THE ADM8832 EVALUATION BOARD
Scanning Mode
To set up the ADM8832 evaluation board in scanning mode,
use the following steps:
1. Connect the scanning mode load resistors.
2. +5VOUT—Connect R1 (insert LK1A, remove LK1C/LK1D)
3. +15VOUT—Connect R4 (insert LK5A )
4. −10VOUT—Connect R6 (insert LK4A )
Note that all other load resistors should be disconnected by
removing their links (see Table 3).
5. Connect VOUT to the ADM8832 LDO (insert LK2A,
remove LK2B).
6. Use 3.3 V logic levels for logic inputs.
7. Connect the following jumpers:
SHDN
—Insert LK8A, remove LK8B
LDO_ON/
OFF
—Insert LK7A, remove LK7B
SCAN/
BLANK
—Insert LK9A, remove LK9B
8. CLKIN—Connect the SMB cable to SK1.
Note that an external clock is not required to be applied to
CLKIN (Pin 9) in this mode.
9. Apply a 3 V supply to J1.
Blanking Mode
To set up the ADM8832 evaluation board in blanking mode,
use the following steps:
1. Connect the blanking mode load resistors.
2. +5VOUT—Connect R3 (insert LK1C, remove LK3A/LK3B)
3. +15VOUT—Connect R5 (insert LK5B)
4. −10VOUT—Connect R7 (insert LK4B)
Note that all other load resistors should be disconnected by
removing their links (see Table 3).
5. Connect VOUT to the ADM8832 LDO (insert LK2A,
remove LK2B).
6. Use 3.3 V logic levels for logic inputs.
7. Connect the following jumpers:
SHDN
—Insert LK8A, remove LK8B
LDO_ON/
OFF
—Insert LK7A, remove LK7B
SCAN/
BLANK
—Insert LK9B, remove LK9A (The signal
must be low for blanking mode.)
8. CLKIN—Connect the SMB cable to SK1.
Note that an external clock must be applied to CLKIN
(Pin 9) in this mode. The frequency of this clock is
nominally 1 kHz (refer to the ADM8832 data sheet for
more details).
9. Apply a 3 V supply to J1.
