reference operations (continued)
ADC reference
The MODE pin is used to select the reference source for the ADC.
D Internal ADC Reference: Connect the MODE pin to AVDD to use the reference source for ADC generated
on the VREF pin. (See VREF REFERENCE described in Table 2) such that (REFTF–REFBF) = VREF and
(REFTF+REFBF)/2 is set to a voltage for optimum operation of the ADC (near AVDD/2).
D External ADC Reference: To supply an external reference source to the ADC, connect the MODE pin to
AGND. An external reference source should be connected to REFTF/REFTS and REFBF/REFBS.
MODE = AGND closes internal switches to allow a Kelvin connection through REFTS/REFBS, and disables
the on-chip amplifiers which drive on to the ADC references. Differential input is not supported
analog input mode
single-ended input
The single-ended input can be configured to work with either an external ADC reference or internal ADC
reference.
D External ADC Reference Mode: A single-ended analog input is accepted at the AIN pin where the input
signal is bounded by the voltages on the REFTS and REFBS pins. Figure 7 shows an example of applying
external reference to REFTS and REFBS pins in which REFTS is connected to the low-impedance 2-V
source and REFBS is connected to the low-impedance 2-V source. REFTS and REFBS may be driven to
any voltage within the supply as long as the difference (REFTS – REFBS) is between 1 V and 2 V as
specified in Table 2. Figure 8 shows an example of external-reference using a Kelvin connection to eliminate
line voltage drop errors.
