Unformatted text preview: General Description The MAX1272/MAX1273 multirange 12-bit data-acquisi- tion 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; ±V REF , ±V REF / 2, 0 to V REF , 0 to V REF / 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 pow- ered 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-cur- rent 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 PDIP package. Both devices are available in the commercial (0°C to +70°C) or extended (-40°C to +85°C) tempera- ture range.
