The MAX1084/MAX1085 10-bit analog-to-digital converters (ADCs) combine a high-bandwidth track/hold, a serial interface with high conversion speed, an internal +2.5V reference, and low power consumption. The MAX1084 operates from a single +4.5V to +5.5V supply; the MAX1085 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 combined with 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 MAX1084/MAX1085 are available in 8-pin SO packages.

These devices are pin-compatible, higher-speed versions of the MAX1242/MAX1243; for more information, refer to the respective data sheets.
