BAND GAP REFERENCE
The ADuC7023 provides an on-chip band gap reference of
2.5 V, which can be used for the ADC and DAC. This internal
reference also appears on the VREF pin. When using the internal
reference, a 0.47 μF capacitor must be connected from the external
VREF pin to AGND to ensure stability and fast response during
ADC conversions. This reference can also be connected to an
external pin (VREF) and used as a reference for other circuits in
the system.
An external buffer is required because of the low drive capability
of the VREF output. A programmable option also allows an
external reference input on the VREF pin.
REFCON Register
Name:
REFCON
Address:
0xFFFF048C
Default value:
0x00
Access:
Read/write
Function:
The band gap reference interface consists
of an 8-bit MMR REFCON described in
Table 30. REFCON MMR Bit Designations
Bit
Description
7 to 1
Reserved.
0
Internal reference output enable.
This bit is set by the user to connect the internal 2.5 V
reference to the VREF pin. The reference can be used
for an external component but needs to be buffered.
This bit is cleared by the user to disconnect the
reference from the VREF pin.
To connect an external reference source to the ADuC7023,
configure REFCON = 0x01. ADC and the DACs can be
configured to use the same or different reference resource. See
Rev. E
