ADC10464 - 具有输入多路复用器和采样/保持功能的 10 位 600 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 ADC10461 and ADC10462 are obsolete. They are 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 dissipate a maximum of only 235mW. These converters perform 10-bit conversion in two lower-resolution “flashes”, yielding a fast A/D without the cost, power consumption, and other problems associated with true flash approaches. Dynamic performance (THD, S/N) is ensured.
The analog input voltage is sampled and held by an internal sampling circuit. Input signals at frequencies from DC to over 200kHz can, therefore, be digitized accurately without the need for an external sample-and-hold circuit.
The ADC10462 and ADC10464 include a “speed-up” pin. Connecting an external resistor between this pin and ground reduces the typical conversion time to as little as 350ns with only a small increase in linearity error.
For ease of interface to microprocessors, the ADC10461, ADC10462, and ADC10464 have been designed to appear as a memory location or I/O port without the need for external interface logic.
