APPLICATIONS INFORMATION
Note that since the amplifier gain error is specified with an
RIN = 100Ω it can be represented as a series resistance,
RP, with value 200mΩ. Using a larger value of RIN can
reduce the gain error since RP will be less as a percentage
as shown in Figure 6.
Supply Rejection: The amplifier supply rejection is a
measure of how the input offset voltage changes with a
change in supply and input common mode voltage. With
114dB, a 10V supply that varies by ±10% will cause the
following error:
2V
V
1.2V
100mV
= 0.0024%
Common Mode Rejection: The amplifier common mode
rejection is a measure of how the input offset voltage
changes as the SENSEHI and SENSELO pins move com-
mon mode. If the inputs are tied to V+ then this error does
not need to be considered because of the way PSRR is
specified (see Note 7). With 103dB, the resulting change
in offset voltage due to a ±10% variation in a 12V battery
connected to SENSEHI, SENSELO voltage creates the
following error:
7V
V
1.2V
100mV
= 0.0084%
Accuracy of External Gain Set Resistors: The gain is set
by external resistors RIN and ROUT. The precision of these
external resistors contributes directly to the system error.
Using 0.1% resistors results in the following error:
2 0.1% = 0.2%
Drift of Gain Set Resistors: The drift of the external gain
set resistors also contributes directly to the system er-
ror. Using resistors with a maximum drift specification of
50ppm/°C results in the following error:
2 50
ppm
°C
100
°C = 1%
Threshold Accuracy: The total error of the comparators
and reference result in the following error:
8mV
400mV
= 2%
Accuracy of External Resistors: The comparator trip point
is set by external resistors R1 and RIN. The precision of
these external resistors contribute directly to the system
error. Using 0.1% resistors results in the following error:
2 0.1% = 0.2%
