Аналого-цифровые преобразователи (АЦП) MAX187BEWE+

АЦП , низкой мощности, 12 бит, 75 Квыборок/с, Несимметричный, SPI, Однополярный, 4.75 В

The MAX187BEWE+ is a +5V, low power serial 12bit analogue to digital converter (ADC) in 16 pin WSOIC package. This device operates from a single +5V supply and accepts 0 to 5V analogue input. It includes 8.5µs successive approximation ADC, fast track/hold (1.5µs), on-chip clock and high speed 3-wire serial interface. The MAX187B digitize signals at 75KSPS throughput rate. An external clock accesses data from interface communicates without external hardware to most digital signal processors and microcontrollers. Power consumption is 7.5mW and reduces to only 10µW in shutdown. Excellent AC characteristics and very low power consumption combined with ease of use and small package size make this converter as ideal device for remote DSP and sensor applications or for circuits where power consumption and space are crucial. Typical application includes data logging, remote digital signal processing and isolated data acquisition.
