MAX1272EUA+ by Analog Devices

Fault-Protected, 12-Bit ADCs with Software-Selectable Input Range


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 power-down modes (delayed standby, immediate standby, delayed full power-down, and immediate full power-down) provide low-current shutdown between conversions. In standby mode, the internal reference buffer remains active, thus eliminating startup delay. The MAX1272/MAX1273 are available in an 8-pin µMAX® package. Both devices are available in the extended (-40°C to +85°C) temperature range.
