Detailed Description
The MAX11644/MAX11645 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 MAX11644/MAX11645
measure either two single-ended or one differential
input(s). 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
MAX11644/MAX11645.
Power Supply
The MAX11644/MAX11645 operate from a single sup-
ply and consume 670μA (typ) at sampling rates up to
94.4ksps. The MAX11645 feature a 2.048V internal ref-
erence and the MAX11644 feature a 4.096V internal ref-
erence. All devices can be configured for use with an
external reference from 1V to VDD.
Analog Input and Track/Hold
The MAX11644/MAX11645 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
connects CT/H between the analog input selected by
CS[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[0] (Table 4).
