General Description
The MAX1084/MAX1085 10-bit analog-to-digital convert-
ers (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 con-
versions.
Low power combined with ease of use and small pack-
age 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.
