Detailed Information
The MAX1407/MAX1408/MAX1409/MAX1414 are low-
power, general-purpose, multichannel DAS featuring a
multiplexed fully differential 16-bit
∑ analog-to-digital
converter (ADC), 10-bit force/sense digital-to-analog
converters (DAC), a real-time clock (RTC) with an
alarm, a bandgap voltage reference, a signal detect
comparator, two power-supply voltage monitors, wake-
up control circuitry, and a high-frequency phase-locked
loop (PLL) clock output all controlled by a 3-wire serial
interface. (See Table 1 for the MAX1407/MAX1408/
MAX1409/MAX1414 feature sets and Figures 1, 2, 3 for
the Functional Diagrams). These DAS directly interface
to various sensor outputs and once configured provide
the stimulus, conditioning, and data conversion, as well
as microprocessor support. Figure 4 is a Typical
Application Circuit for the MAX1407/MAX1414.
The 16-bit
∑ ADC is capable of programmable contin-
uous conversion rates of 30Hz or 60Hz and gains of
1/3, 1, and 2V/V to suit applications with different power
and dynamic range constraints. The force/sense DACs
provide 10-bit linearity for precise sensor applications.

FUNCTION
20
14
INT
Active-Low Interrupt Output. INT goes low when the PLL output is ready,
when the signal-detect comparator is tripped, or when the alarm is triggered.
21
15
DOUT
Serial Data Output. DOUT outputs serial data from the internal shift register
on SCLK’s falling edge. When CS is high, DOUT is three-stated.
22
16
DIN
Serial Data Input. Data on DIN is written to the input shift register and is
clocked in at SCLK’s rising edge when CS is low.
23
17
SCLK
Serial Clock Input. Apply an external serial clock to transfer data to and from
the device. This serial clock can be continuous, with data transmitted in a
train of pulses, or intermittent while CS is low.
24
18
CS
Active-Low Chip-Select Input. CS is used to select the active device in
systems with more than one device on the serial bus. Data will not be
clocked into DIN unless CS is low. When CS is high, DOUT is three-stated.

19
DGND
Digital Ground. Reference point for digital circuitry.
