The MAX11606–MAX11611 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 MAX11606/MAX11607
are 4-channel ADCs, the MAX11608/MAX11609 are
8-channel ADCs, and the MAX11610/MAX11611 are
12-channel ADCs. These devices feature a high-speed
2-wire serial interface supporting data rates up to
SDA

1.7MHz. Figure 2 shows the simplified internal structure
for the MAX11610/MAX11611.
The MAX11606–MAX11611 operates from a single sup-
ply and consumes 670µA (typ) at sampling rates up to
94.4ksps. The MAX11607/MAX11609/MAX11611 feature
a 2.048V internal reference and the MAX11606/
MAX11608/MAX11610 feature a 4.096V internal refer-
ence. All devices can be configured for use with an
external reference from 1V to V
The MAX11606–MAX11611 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 C
CS[3:0] (see the Configuration/Setup Bytes (Write
Cycle) section) and GND (Table 3). In differential mode,
the analog- input multiplexer connects C
- analog inputs selected by CS[3:0] (Table 4).
During the acquisition interval, the T/H switches are in
