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 RIN values. Trace resistance
to the –IN terminals will increase the effective RIN 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 RIN.
Selection of External Output Resistor, ROUT
The output resistor, ROUT, determines how the output cur-
rent is converted to voltage. VOUT is simply IOUT ROUT. In
choosing an output resistor, the maximum output voltage
must rst be considered. If the circuit following is a buf-
fer or ADC with limited input range, then ROUT must be
chosen so that IOUT(MAX) ROUT is less than the allowed
maximum input range of this circuit.
In addition, the output impedance is determined by ROUT. 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 ROUT 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 ROUT,
then the accuracy of VOUT will be reduced by 1% since:
