MAX1358B
Detailed Description
The MAX1358B DAS features a multiplexed differential
16-bit ADC, 10-bit force-sense DACs, an RTC with an
alarm, a selectable bandgap voltage reference, a signal-
detect comparator, 1.8V and 2.7V voltage monitors, and
wake-up control circuitry, all controlled by a 4-wire serial
interface (see Figure 3 for the functional diagram).
The DAS directly interfaces to various sensor outputs
and, once configured, provides the stimulus, signal con-
ditioning, and data conversion, as well as P support.
See the
Applications section for sample MAX1358B
applications.
The 16-bit ADC features programmable continuous con-
version rates as shown in Table 4, and gains of 1, 2, 4,
and 8 (Table 5) to suit applications with different power
16-Bit, Data-Acquisition System with ADC, DACs,
UPIOs, RTC, Voltage Monitors, and Temp Sensor
