AD7813: +2.7 V至+5.5 V、8/10位、400 kSPS采样ADC
AD7813是一款高速、微处理器兼容型、8/10位模数转换器（ADC），最大吞吐量为400 kSPS。该转换器采用+2.7 V至+5.5 V单电源供电，内置2.3 毫秒（ms）逐次逼近型模数转换器、采样保持电路、片内时钟振荡器和8位宽并行接口。利用该并行接口，可方便地与微处理器和DSP进行接口。10位转换结果的读取通过两次8位读取操作来完成。第一次读取操作访问ADC转换结果的8个MSB，第二次读取操作访问它的2个LSB。AD7813仅使用地址解码逻辑，因此很容易实现到微处理器地址空间的映射。在省电模式下工作时，AD7813会在一次转换结束时自动关断，并在新转换开始时自动上电。当吞吐量较低时，此特性可显著降低器件的功耗。AD7813也可在高速模式下工作，此时该器件在两次转换之间不关断。在这种模式下工作时，该器件能提供400 kSPS吞吐量。AD7813提供三种封装：16引脚、0.3英寸宽、小型塑料双列直插式封装（DIP）；16引脚、0.15英寸宽、窄体小形集成封装（SOIC）；以及16引脚超薄紧缩小型封装（TSSOP）。
The AD7813 is a high speed, microprocessor-compatible, 8-/10-bit analog-to-digital converter with a maximum through-put of 400 kSPS. The converter operates off a single +2.7 V to +5.5 V supply and contains a 2.3 ms successive approximation A/D converter, track/hold circuitry, on-chip clock oscillator and 8-bit wide parallel interface. The parallel interface is designed to allow easy interfacing to microprocessors and DSPs. The 10-bit conversion result is read by carrying out two 8-bit read operations. The first read operation accesses the 8 MSBs of the ADC conversion result and the second read accesses the 2 LSBs. Using only address decoding logic the AD7813 is easily mapped into the microprocessor address space.
When used in its power-down mode, the AD7813 automatically powers down at the end of a conversion and powers up at the start of a new conversion. This feature significantly reduces the power consumption of the part at lower throughput rates. The AD7813 can also operate in a high speed mode where the part is not powered down between conversions. In this mode of operation the part is capable of providing 400 kSPS throughput.
The part is available in a small, 16-pin, 0.3" wide, plastic dual-in- line package (DIP), in a 16-pin, 0.15" wide, narrow body small outline IC (SOIC) and in a 16-pin thin shrink small outline package (TSSOP).
