APPLICATIONS INFORMATION
Care should be taken when designing the printed circuit
board layout to minimize input trace resistance (to Pins 5,
6, 7 and 8), especially for small R
IN
values. Trace resistance
to the –IN terminals will increase the effective R
IN
value,
causing a gain error. Trace resistance on +IN terminals will
have an effect on offset error. These errors are described
in more detail later in this data sheet. In addition, internal
device resistance will add approximately 0.3
Ω
to R
IN
.
Selection of External Output Resistor, R
OUT
The output resistor, R
OUT
, determines how the output cur-
rent is converted to voltage. V
OUT
is simply I
OUT
R
OUT
. In
choosing an output resistor, the maximum output voltage
must first be considered. If the circuit following is a buf-
fer or ADC with limited input range, then R
OUT
must be
chosen so that I
OUT(MAX)
R
OUT
is less than the allowed
maximum input range of this circuit.
In addition, the output impedance is determined by R
OUT
. If
the circuit to be driven has high enough input impedance,
then almost any useful output impedance will be accept-
able. However, if the driven circuit has relatively low input
impedance or draws spikes of current, as an ADC might
do, then a lower R
OUT
value may be required in order to
preserve the accuracy of the output. As an example, if the
input impedance of the driven circuit is 100 times R
OUT
,
then the accuracy of V
OUT
will be reduced by 1% since:
