The MAX1284/MAX1285 12-bit analog-to-digital converters (ADCs) combine a high-bandwidth track/hold (T/H), a serial interface with high conversion speed, an internal +2.5V reference, and low power consumption. The MAX1284 operates from a single +4.5V to +5.5V supply; the MAX1285 operates from a single +2.7V to +3.6V supply. The 3-wire serial interface connects directly to SPI™/QSPI™/MICROWIRE™ devices without external logic. The devices use an external serial-interface clock to perform successive-approximation analog-to-digital conversions. Low power, ease of use, and small package size make these converters ideal for remote-sensor and data-acquisition applications or for other circuits with demanding power consumption and space requirements. The MAX1284/MAX1285 are available in 8-pin SO packages. These devices are pin-compatible, higher-speed versions of the MAX1240/MAX1241; for more information, refer to the respective data sheets.
