MAX1067ACEE中文资料美信数据手册PDF规格书

General Description

The MAX1067/MAX1068 low-power, multichannel, 14-bit analog-to-digital converters (ADCs) feature a successive-approximation ADC, integrated +4.096V reference, a reference buffer, an internal oscillator, automatic power-down, and a high-speed SPI™/QSPI™/MICROWIRE™-compatible interface. The MAX1067/MAX1068 operate with a single +5V analog supply and feature a separate digital supply, allowing direct interfacing with +2.7V to +5.5V digital logic.
