3.0 ADC082S101 TRANSFER FUNCTION
The output format of the ADC082S101 is straight binary.
Code transitions occur midway between successive integer
LSB values. The LSB width for the ADC082S101 is V
A
/256.
The ideal transfer characteristic is shown in
Figure 3
. The
transition from an output code of 0000 0000 to a code of
0000 0001 is at 1/2 LSB, or a voltage of V
A
/512. Other code
transitions occur at steps of one LSB.
4.0 TYPICAL APPLICATION CIRCUIT
A typical application of the ADC082S101 is shown in
Figure
4
. Power is provided in this example by the National Semi-
conductor LP2950 low-dropout voltage regulator, available in
a variety of fixed and adjustable output voltages. The power
supply pin is bypassed with a capacitor network located
close to the ADC082S101. Because the reference for the
ADC082S101 is the supply voltage, any noise on the supply
will degrade device noise performance. To keep noise off the
supply, use a dedicated linear regulator for this device, or
provide sufficient decoupling from other circuitry to keep
noise off the ADC082S101 supply pin. Because of the
ADC082S101’s low power requirements, it is also possible to
use a precision reference as a power supply to maximize
performance. The four-wire interface is also shown con-
nected to a microprocessor or DSP.
