Overview
MAX1272/MAX1273 19-2921; Rev 3; 12/11 EVAALVUAAILTAIOBNLEKIT Fault-Protected, 12-Bit ADCs with Software-Selectable Input Range General Description The MAX1272/MAX1273 multirange 12-bit data-acquisition systems (DAS) operate with a single 5V supply.
The software-programmable analog input accepts a variety of voltage ranges: ±10V, ±5V, 0 to 10V, 0 to 5V for the MAX1272; ±VREF, ±VREF/2, 0 to VREF, 0 to VREF/2 for the MAX1273.
The software-selectable extended analog input range increases the effective dynamic range to 14 bits and provides the flexibility to interface 4–20mA powered sensors directly to a single 5V system.
In addition, the MAX1272 provides fault protection to ±12V.
Other features include a 5MHz track/hold (T/H) bandwidth, 87ksps throughput rate, and internal (4.
096V) or external (2.
40V to 4.
18V) reference.
The MAX1272/MAX1273 serial interfaces connect directly to SPI/QSPI™/MICROWIRE®-compatible devices without any external logic.
Four software-programmable pow...
