The MAX1280/MAX1281 12-bit ADCs combine an 8-channel analog-input multiplexer, high-bandwidth track/hold, and serial interface with high conversion speed and low power consumption. The MAX1280 operates from a single +4.5V to +5.5V supply; the MAX1281 operates from a single +2.7V to +3.6V supply. Both devices' analog inputs are software configurable for unipolar/bipolar and single-ended/pseudo-differential operation.
The 4-wire serial interface connects directly to SPI™/QSPI™/MICROWIRE™ devices without external logic. A serial strobe output allows direct connection to TMS320-family digital signal processors. The MAX1280/MAX1281 use an external serial-interface clock to perform successive-approximation analog-to-digital conversions. Both parts feature an internal +2.5V reference and a reference-buffer amplifier with a ±1.5% voltage-adjustment range. An external reference with a 1V to VDD1 range may also be used.
The MAX1280/MAX1281 provide a hard-wired active-low SHDN pin and four software-selectable power modes (normal operation, reduced power, fast power-down, and full power-down). These devices can be programmed to automatically shut down at the end of a conversion or to operate with reduced power. When using the power-down modes, accessing the serial interface automatically powers up the devices, and the quick turn-on time allows them to be powered down between all conversions. This technique can cut supply current to under 100µA at reduced sampling rates.
The MAX1280/MAX1281 are available in 20-pin TSSOP packages. These devices are higher-speed versions of the MAX146/MAX147 (for more information, see the respective data sheet).

Evaluation Kits 1
MAX1280EVC16
Evaluation Kit/Evaluation System for the MAX1280
Product Detail
The MAX1280 evaluation system (EV system) is a complete, 8-channel data-acquisition system consisting of a MAX1280 evaluation kit (EV kit), Maxim 68HC16MODULE-DIP microcontroller (µC) module, and USBTO232. The MAX1280 is a high-speed, multi-channel, 12-bit data-acquisition system. Windows® 98/2000/XP-compatible software provides a handy user interface to exercise the MAX1280's features.
Order the complete EV system (MAX1280EVC16) for a comprehensive evaluation of the MAX1280 using a PC. Order the EV kit (MAX1280EVKIT) if the 68HC16MODULE-DIP module has already been purchased with a previous Maxim EV system, or for custom use in other µC-based systems.
