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
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
inputs ranging from 0 to V
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.
