Description
The MAX1086–MAX1089 are low-cost, micropower, serial 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 interface. Power consumption is only 0.5mW (VDD = +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 VREF. The MAX1088/MAX1089 accept true-differential inputs ranging from 0 to VREF. 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 consumption and minimal space.
