Detailed Description
The MAX11612–MAX11617 analog-to-digital converters
(ADCs) use successive-approximation conversion tech-
niques and fully differential input track/hold (T/H) cir-
cuitry to capture and convert an analog signal to a
serial 12-bit digital output. The MAX11612/MAX11613
are 4-channel ADCs, the MAX11614/MAX11615 are
8-channel ADCs, and the MAX11616/MAX11617 are
12-channel ADCs. These devices feature a high-speed,
2-wire serial interface supporting data rates up to
1.7MHz. Figure 2 shows the simplified internal structure
for the MAX11616/MAX11617.
Power Supply
The MAX11612–MAX11617 operate from a single sup-
ply and consume 670A (typ) at sampling rates up to
94.4ksps. The MAX11613/MAX11615/MAX11617 fea-
ture a 2.048V internal reference and the MAX11612/
MAX11614/MAX11616 feature a 4.096V internal refer-
ence. All devices can be configured for use with an
external reference from 1V to VDD.
Analog Input and Track/Hold
The MAX11612–MAX11617 analog-input architecture
contains an analog-input multiplexer (mux), a fully dif-
ferential track-and-hold (T/H) capacitor, T/H switches, a
comparator, and a fully differential switched capacitive
digital-to-analog converter (DAC) (Figure 4).
In single-ended mode, the analog input multiplexer con-
nects CT/H between the analog input selected by
CS[3:0] (see the
Configuration/Setup Bytes (Write Cycle)
section) and GND (Table 3). In differential mode, the
analog-input multiplexer connects CT/H to the + and -
analog inputs selected by CS[3:0] (Table 4).
