MAX1067/MAX1068是低功耗、多通道、14位模拟数字转换器(ADC)，具有逐次逼近ADC、集成+4.096V参考、参考缓冲器、内部振荡器、自动电源关闭和高速SPI™/QSPI™/MICROWIRE™兼容接口。MAX1067/MAX1068使用单个+5V模拟电源，并具有单独的数字电源，允许直接与+2.7V至+5.5V数字逻辑进行接口。MAX1067/MAX1068在使用外部参考时在200ksps时仅消耗2.9mA（AVDD = DVDD = +5V）。AutoShutdown™将供电电流降低至145µA，在10ksps时降低至不到10µA，在降低采样速率时降低。MAX1067包括4通道输入多路复用器，MAX1068接受多达8个模拟输入。此外，数字信号处理器(DSP)触发转换通过MAX1068提供的DSP帧同步输入和输出得到简化。MAX1068包括一个数据位传输输入，用于在8位宽或16位宽数据传输模式之间进行选择。两种器件都具有扫描模式，该扫描模式可将每个通道逐个转换或将一个通道连续转换。出色的动态性能和低功耗，加上易于使用和集成参考，使MAX1067/MAX1068成为控制和数据采集操作或其他对功耗和空间要求苛刻的应用的理想选择。MAX1067采用16引脚QSOP封装，MAX1068采用

The MAX1067/MAX1068 low-power, multichannel, 14-bit analog-to-digital converters (ADCs) feature a suc- cessive-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. The MAX1067/MAX1068 consume only 2.9mA (AVDD = DVDD = +5V) at 200ksps when using an external refer- ence. AutoShutdown™ reduces the supply current to 145µA at 10ksps and to less than 10µA at reduced sam- pling rates. The MAX1067 includes a 4-channel input multiplexer, and the MAX1068 accepts up to eight analog inputs. In addition, digital signal processor (DSP)-initiated con- versions are simplified with the DSP frame-sync input and output featured in the MAX1068. The MAX1068 includes a data-bit transfer input to select between 8-bit-wide or 16- bit-wide data-transfer modes. Both devices feature a scan mode that converts each channel sequentially or one channel continuously. Excellent dynamic performance and low power, com- bined with ease of use and an integrated reference, make the MAX1067/MAX1068 ideal for control and data- acquisition operations or for other applications with demanding power consumption and space require- ments. The MAX1067 is available in a 16-pin QSOP package, and the MAX1068 is available in
