I. Device Description
A. General
The MAX1287 is a low-cost, micropower, serial output 12-bit analog-to-digital converter (ADC) available in a tiny 8-pin
SOT23. The MAX1287 operates 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
(V_DD = +2.7V) at the maximum sampling rate of 150ksps. AutoShutdown™ (0.2µA) between conversions results in
reduced power consumption at slower throughput rates. The MAX1287 provides 2-channel, single-ended operations
and accept input signals from 0 to V_REF. 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.
