Detailed Description
The MAX11646/MAX11647 ADCs use successive-
approximation conversion techniques and fully differen-
tial input T/H circuitry to capture and convert an analog
signal to a serial 10-bit digital output. The
MAX11646/MAX11647 measure either two single-
ended inputs or one differential input. 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 MAX11646/MAX11647.
Power Supply
The MAX11646/MAX11647 operate from a single supply
and consume 670A (typ) at sampling rates up to
94.4ksps. The MAX11647 features a 2.048V internal ref-
erence and the MAX11646 features a 4.096V internal ref-
erence. These devices can be configured for use with an
external reference from 1V to VDD.
Analog Input and Track/Hold
The MAX11646/MAX11647 analog input architecture
contains an analog input multiplexer (mux), a fully dif-
ferential 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 CS0
(see the
Configuration/Setup Bytes (Write Cycle) sec-
tion) and GND (Table 3). In differential mode, the analog
input multiplexer connects CT/H to the + and - analog
inputs selected by CS0 (Table 4).
During the acquisition interval, the T/H switches are in
the track position and CT/H charges to the analog input
signal. At the end of the acquisition interval, the T/H
switches move to the hold position retaining the charge
on CT/H as a stable sample of the input signal.
