AD7810: 2.7 V至5.5 V、2 ms、10位ADC，采用8引脚microSOIC/DIP封装
AD7810是一款高速、低功耗、10位模数转换器（ADC），采用2.7 V至5.5 V单电源供电。该器件内置一个2 微秒（µs）逐次逼近型模数转换器（固有采样保持功能）、一个伪差分输入和一个可与大多数微控制器接口的高速串行接口，额定温度范围为-40°C至+105°C。AD7810采用一种能够在一次转换结束时对CONVST（转换开始）信号状态进行采样的技术，因此可以在自动省电模式下工作。在这种模式下工作时，AD7810会在一次转换结束时自动关断，并在新转换开始时自动“唤醒”。当吞吐量较低时，此特性可显著降低器件的功耗。AD7810也可在一种高速模式下工作，此时该器件在两次转换之间不关断。在这种高速模式下工作时，AD7810的转换时间为2 微秒（µs）。最大吞吐量取决于微控制器串行接口的速度。AD7810采用三种封装：8引脚、0.3英寸宽、小型塑料双列直插式封装（小型DIP）；8引脚小形集成封装（SOIC）；以及8引脚microSOIC封装。
The AD7810 is a high speed, low power, 10-bit A/D converter that operates from a single 2.7 V to 5.5 V supply. The part contains a 2 µs successive approximation A/D converter, with inherent track/hold functionality, a pseudo differential input and a high speed serial interface that interfaces to most microcontrollers. The AD7810 is fully specified over a temperature range of -40°C to +105°C.
By using a technique that samples the state of the CONVST (convert start) signal at the end of a conversion, the AD7810 may be used in an automatic power-down mode. When used in this mode, the AD7810 automatically powers down at the end of a conversion and "wakes up" at the start of a new conversion. This feature significantly reduces the power consumption of the part at lower throughput rates. The AD7810 can also operate in a high speed mode where the part is not powered down between conversions. In this high speed mode of operation, the conversion time of the AD7810 is 2 µs. The maximum throughput rate is dependent on the speed of the serial interface of the microcontroller.The part is available in a small 8-pin, 0.3" wide, plastic dual-in-line package (mini-DIP); in an 8-lead, small outline IC (SOIC); and in an 8-lead microSOIC package
