General Description

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

= +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.
