Applications Information
(Continued)
The V
+ F and V
F pins should each be bypassed to
AGND with 10 μF tantalum or electrolytic and 0.1 μF ceramic
capacitors. The circuit of Figure 6may be used if it is desired
to obtain precise reference voltages. The LMC6082 in this
circuit was chosen for its low offset voltage, low voltage ca-
pability and low cost.
Since the current flowing through the sense lines (those lines
associated with V
+ S and V
S) is essentially zero,
there is negligible voltage drop across any resistance in se-
ries with these sense pins and the voltage at the inverting in-
put of the op-amp accurately represents the voltage at the
top (or bottom) of the ladder. The op-amp drives the force in-
put, forcing the voltage at the ends of the ladder to equal the
voltage at the op-amp’s non-inverting input, plus any offset
voltage. For this reason, op-amps with low V
OS
, such as the
LMC6081 and LMC6082, should be used for this application.
Voltages at the reference sense pins (V
+ S and V
S)
should be within the range specified in the Operating Ratings
table (2.3V to 4.0V for V
+ and 1.3V to 3.0V for V
).
Any device used to drive the reference pins should be able to
source sufficient current into the V
+ F pin and sink suffi-
cient current from the V
F pin when the ladder is at its
minimum value of 850 Ohms.
The reference voltage at the top of the ladder (V
+) may
take on values as low as 1.0V above the voltage at the bot-
tom of the ladder (V
) and as high as (V
A
- 1.0V) Volts.
The voltage at the bottom of the ladder (V
) may take on
values as low as 1.3 Volts and as high as 3.0V. However, to
minimize noise effects and ensure accurate conversions, the
total reference voltage range (V
REF
+ - V
REF
) should be a
minimum of 2.0V and a maximum of 2.7V.
