General Desc ription
The MAX1286–MAX1289 are low-cost, micropower, seri-
al output 12-bit analog-to-digital converters (ADCs)
available in a tiny 8-pin SOT23. The MAX1286/MAX1288
operate with a single +5V supply. The MAX1287/
MAX1289 operate with a single +3V supply. The
devices feature a successive-approximation ADC, auto-
matic shutdown, fast wakeup (1.4μs), and a high-speed
3-wire interface. Power consumption is only 0.5mW
(V
DD
= +2.7V) at the maximum sampling rate of
150ksps. AutoShutdown (0.2μA) between conversions
results in reduced power consumption at slower
throughput rates. The MAX1286/MAX1287 provide
2-channel, single-ended operations and accept input
signals from 0 to V
REF
. The MAX1288/MAX1289 accept
true-differential inputs ranging from 0 to V
REF
. Data is
accessed using an external clock through the 3-wire
SPI /QSPI /MICROWIRE –compatible serial inter-
face. Excellent dynamic performance, low power, ease
of use, and small package size make these converters
ideal for portable battery-powered data-acquisition
applications, and for other applications that demand low
power consumption and minimal space.
