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
DD
= +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
V
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.
