Аналого-цифровые преобразователи (АЦП) MAX11190ATE+T

АЦП , 12 бит, 3 Мвыборок/с, Несимметричный, SPI, Однополярный, 2.2 В

The MAX11190ATE+T is a 4-channel, dual simultaneous sampling, 12bit, 3Msps SAR ADC in 16 pin TQFN package. This high speed, low power, successive approximation ADC includes high-dynamic range sample-and-holds and a high-speed serial interface. Digital output supply allows serial interface to directly connect to 1.5V, 1.8V, 2.5V or 3V digital systems. This ADC accepts a full-scale input from 0V to reference voltage. Device features two dual, single-ended analogue inputs connected to two ADC cores using 2:1 MUXs. The device also includes a separate supply input for data interface and dedicated inputs for reference voltage, full power-down mode and fast wake-up for optimal power management and a high-speed 3-wire serial interface. The excellent dynamic performance, low voltage, low power, ease of use and small package size makes this converter ideal for simultaneous data-acquisition applications and for other applications that demand low power consumption and minimal space.
