ADC10664 - 具有输入多路复用器和采样/保持功能的 10 位 360 ns A/D 转换器 - 精密ADC(<=10MSPS) - 模数转换器 - TI公司（Texas Instruments，德州仪器）
NOTE: The ADC10662 is obsolete. It is described here for reference only.
Using an innovative, patented multistep (U.S. Patent Number 4918449) conversion technique, these 10-bit CMOS analog-to-digital converters offer sub-microsecond conversion times yet dissipating a maximum of only 235mW. These converters perform 10-bit conversions in two lower-resolution “flashes”, yielding a fast A/D without the cost, power consumption, and other problems associated with true flash approaches. In addition to standard static performance specifications (Linearity, Full-Scale Error, etc.), dynamic performance (THD, S/N) is ensured.
The analog input voltage ADC is sampled and held by an internal sampling circuit. Input signals at frequencies from DC to over 250kHz can therefore be digitized accurately without the need for an external sample-and-hold circuit.
Connecting an external resistor between the “speed-up” pin and ground reduces the typical conversion time to as little as 360ns for a small linearity sacrifice.
For ease of interface to microprocessors, the ADC10662 and ADC10664 have been designed to appear as a memory location or I/O port without the need for external interface logic.
