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.
