MAX1089EKA-T中文资料美信数据手册PDF规格书

General 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.
