General Description

The MAX1086–MAX1089 are low-cost, micropower, ser-

ial output 10-bit analog-to-digital converters (ADCs)

available in a tiny 8-pin SOT23. The MAX1086/MAX1088

operate with a single +5V supply. The MAX1087/MAX1089

operate with a single +3V supply. The devices feature a

successive-approximation ADC, automatic shutdown,

fast wake-up (1.4µs), and a high-speed 3-wire inter-

face. Power consumption is only 0.5mW (V

= +2.7V)

at the maximum sampling rate of 150ksps.

Autoshutdown™ (0.1µA) between conversions results in

reduced power consumption at slower throughput

rates.

The MAX1086/MAX1087 provide 2-channel, single-

ended operation and accept input signals from 0 to

REF

. The MAX1088/MAX1089 accept true-differential

inputs ranging from 0 to V

REF

. Data is accessed using

an external clock through the 3-wire SPI™, QSPI™, and

MICROWIRE™–compatible serial interface. 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 con-

sumption and minimal space.
