General Description
The MAX1284/MAX1285 12-bit analog-to-digital con-
verters (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-acqui-
sition 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 ver-
sions of the MAX1240/MAX1241. Refer to the respec-
tive data sheets for more information.
