EVALUATION KIT AVAILABLE 150ksps, 10-Bit, 2-Channel Single-Ended, and 1-Channel True-Differential ADCs in SOT23 and TDFN MAX1086–MAX1089 General Description Features
The MAX1086–MAX1089 are low-cost, micropower, ser- o
Single-Supply Operation
ial output 10-bit analog-to-digital converters (ADCs)
+3V (MAX1087/MAX1089)
available in a tiny 8-pin SOT23. The MAX1086/MAX1088
+5V (MAX1086/MAX1088)
operate with a single +5V supply. The MAX1087/MAX1089 o
AutoShutdown Between Conversions
operate with a single +3V supply. The devices feature a o
Low Power
successive-approximation ADC, automatic shutdown,
200µA at 150ksps
fast wake-up (1.4µs), and a high-speed 3-wire inter-

face. Power consumption is only 0.5mW (VDD = +2.7V)
65µA at 50ksps
at the maximum sampling rate of 150ksps.
13µA at 10ksps
AutoShutdown™ (0.1µA) between conversions results in
1.5µA at 1ksps
reduced power consumption at slower throughput rates.
0.2µA in Shutdown
The MAX1086/MAX1087 provide 2-channel, single- o
True-Differential Track/Hold, 150kHz Sampling Rate
ended operation and accept input signals from 0 to o
Software-Configurable Unipolar/Bipolar
VREF. The MAX1088/MAX1089 accept true-differential
