MAX187
Description
The MAX187/MAX189 serial 12-bit analog-to-digital converters (ADCs) operate from a single +5V supply and accept a 0V to 5V analog input. Both parts feature an 8.5µs successive-approximation ADC, a fast track/hold (1.5µs), an on-chip clock, and a high-speed 3-wire serial interface. The MAX187/MAX189 digitize signals at a 75ksps throughput rate. An external clock accesses data from the interface, which municates without external hardware to most digital signal processors and microcontrollers. The interface is patible with SPI™, QSPI™, and Microwire™. The MAX187 has an on-chip buffered reference, and the MAX189 requires an external reference. Both the MAX187 and MAX189 save space with 8-pin DIP and 16-pin SO packages. Power consumption is 7.5m W and reduces to only 10µW in shutdown. Excellent AC characteristics and very low power consumption bined with ease of use and small package size make these converters ideal for remote DSP and sensor applications, or for circuits where...
