The MAX1270/MAX1271 are multirange, 12-bit data-acquisition systems (DAS) that require only a single +5V supply for operation, yet accept signals at their analog inputs that may span above the power-supply rail and below ground. These systems provide eight analog input channels that are independently software programmable for a variety of ranges: ±10V, ±5V, 0 to +10V, 0 to +5V for the MAX1270; ±VREF, ±VREF/2, 0 to VREF, 0 to VREF/2 for the MAX1271. This range switching increases the effective dynamic range to 14 bits and provides the flexibility to interface 4-20mA, ±12V, and ±15V powered sensors directly to a single +5V system. In addition, these converters are fault protected to ±16.5V; a fault condition on any channel will not affect the conversion result of the selected channel. Other features include a 5MHz bandwidth track/hold, software-selectable internal/external clock, 110ksps throughput rate, and internal 4.096V or external reference operation.
The MAX1270/MAX1271 serial interface directly connects to SPI™/QSPI™ and MICROWIRE™ devices without external logic.
A hardware shutdown input (SHDN-bar) and two software-programmable power-down modes, standby (STBYPD) or full power-down (FULLPD), are provided for low-current shutdown between conversions. In standby mode, the reference buffer remains active, eliminating start-up delays.
The MAX1270/MAX1271 are available in 24-pin narrow DIP or space-saving 28-pin SSOP packages.

Evaluation Kits 3
MAX1270EVSYS
Evaluation Kit/Evaluation System for the MAX1270, MAX1271, MAX127, and MAX128
Product Detail
The MAX1270 evaluation system (EV system) is a complete, 8-channel data-acquisition system consisting of a MAX1270 evaluation kit (EV kit) and a Maxim 68HC16MODULE-DIP microcontroller (µC) module. It is designed to evaluate the MAX1270/MAX1271, a multirange, 8-channel, 12-bit data acquisition system. Windows® 3.1/Windows 95 software provides a handy user interface to exercise the MAX1270's features.
Order the complete EV system (MAX1270EVC16) for comprehensive evaluation of the MAX1270 or MAX1271 using a personal computer. Order the EV kit (MAX1270EVKIT) if you have already purchased the µC module (68HC16MODULE-DIP) with another Maxim EV system or for custom use in other µC-based systems.
The MAX1270 EV kit can also be used to evaluate the MAX127 and MAX128.
Applications
- Automated Test Equipment (ATE)
- Battery-Powered Applications
- Data Acquisition
- Industrial Control Systems
