MAX1273 - 12-Bit ADCs

Download the MAX1273 datasheet PDF. This datasheet also covers the MAX1272 variant, as both devices belong to the same 12-bit adcs family and are provided as variant models within a single manufacturer datasheet.

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.

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™/.

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.
