Detailed Description
Converter Operation
The MAX1165/MAX1166 use a successive-approxima-
tion (SAR) conversion technique with an inherent track-
and-hold (T/H) stage to convert an analog input into a
16-bit digital output. Parallel outputs provide a high-
speed interface to most microprocessors (Ps). The
Functional Diagram shows a simplified internal archi-
tecture of the MAX1165/MAX1166. Figure 3 shows a
typical application circuit for the MAX1166.
Analog Input
The equivalent input circuit is shown in Figure 4. A
switched capacitor digital-to-analog converter (DAC)
provides an inherent T/H function. The single-ended
input is connected between AIN and AGND.
Input Bandwidth
The ADC’s input-tracking circuitry has a 4MHz small-
signal bandwidth, so it is possible to digitize high-
speed transient events and measure periodic signals
with bandwidths exceeding the ADC’s sampling rate by
using undersampling techniques. To avoid aliasing of
unwanted high-frequency signals into the frequency
band of interest, use anti-alias filtering.
Analog Input Protection
Internal protection diodes, which clamp the analog
input to AVDD and/or AGND, allow the input to swing
from AGND - 0.3V to AVDD + 0.3V, without damaging
the device.
If the analog input exceeds 300mV beyond the sup-
plies, limit the input current to 10mA.
