3.0 ADC102S101 TRANSFER FUNCTION
The output format of the ADC102S101 is straight binary. Code transitions occur midway between successive integer LSB values.
The LSB width for the ADC102S101 is V
code of 00 0000 0000 to a code of 00 0000 0001 is at 1/2 LSB, or a voltage of V
one LSB.
4.0 TYPICAL APPLICATION CIRCUIT
A typical application of the ADC102S101 is shown in
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 ADC102S101. Because the reference for the AD-
C102S101 is the supply voltage, any noise on the supply will

supply, use a dedicated linear regulator for this device, or
provide sufficient decoupling from other circuitry to keep noise

ADC102S101's low power requirements, it is also possible to
use a precision reference as a power supply to maximize per-
formance. The four-wire interface is shown connected to a
microprocessor or DSP.
