Description

The MAX1286–MAX1289 are low-cost, micropower, serial output 12-bit analog-to-digital converters (ADCs) available in a tiny 8-pin SOT23 and an 8-pin TDFN. 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, automatic shutdown, fast wakeup (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™ (0.2µA) 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 VREF. The MAX1288/MAX1289 accept true-differential inputs ranging from 0 to VREF. Data is accessed using an external clock through the 3-wire SPI™-/QSPI™-/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.
