Аналого-цифровые преобразователи (АЦП) MAX170DCPA+

АЦП , высокоскоростной, 12 бит, 125 Квыборок/с, Несимметричный, SPI, Биполярный (+/-), 4.75 В

The MAX170DCPA+ is a serial output, 5.6µs, 12bit ADC with reference in 8 pin DIP package. The complete CMOS 12bit ADC that combines high speed and accurate performance with a cost and space saving serial interface. It uses a high speed DAC and an accurate comparator in a successive approximation loop to achieve a 5.6µs conversion time. An on chip buried zener reference provides low drift performance over the full temperature range. External components are limited only to supply and reference decoupling capacitors. The CLOCK input can be driven from an external clock source such as a divided down microprocessor clock. The MAX170 is designed to work with general purpose serial to parallel converters such as the 74HC595. It can also be used with digital signal processors such as the TMS32020, TMS320C25, NEC µPD7720 or the DSP56000. The MAX170 has a three wire interface that serially outputs a leading one followed by 12 data bits (MSB first).
