The MAX1003 features a proprietary encoding scheme

Os c illa t o r Circ u it

The MAX1003 includes a differential oscillator, which is

controlled by an external parallel resonant (tank) net-

work as shown in Figure 6. Alternatively, the oscillator

may be overdriven with an external clock source as

shown in Figure 7.

that ensures no more than 1LSB dynamic encoding

e rror. Dyna mic e nc od ing e rrors re s ulting from

metastable states may occur when the analog input

voltage, at the time the sample is taken, falls close to

the decision point for any one of the input comparators.

The resulting output code for typical converters can be

incorrect, including false full- or zero-scale outputs. The

MAX1003’s unique design reduces the magnitude of

this type of error to 1LSB.

Internal Clock Operation (Tank)

If the tank circuit is used, the resonant inductor should

have a sufficiently high Q and a self-resonant frequen-

cy (SRF) of at least twice the intended oscillator fre-

q ue nc y. Coilc ra ft’s 1008HS-221, with a n SRF of

700MHz and a Q of 45, works well for this application.

Generate different clock frequency ranges by adjusting

varactor and tank elements.

MAX103

In t e rn a l Vo lt a g e Re fe re n c e

An internal buffered bandgap reference is included on

the MAX1003 to drive the ADCs’ reference ladders. The

on-chip reference and buffer eliminate any external

(high-impedance) connections to the reference ladder,

minimizing the potential for noise coupling from exter-

nal circuitry while ensuring that the voltage reference,

input amplifier, and reference ladder track well with

variations of temperature and power supplies.

An internal clock-driver buffer is included to provide

sharp clock edges to the internal flash comparators.

The buffer ensures that the comparators are simultane-

ously clocked, maximizing the ADCs’ effective number

of bits (ENOB) performance.
