The MAX187CCPA IC serial 12-bit analog-to-digital converters (ADCs) operate from a single +5V supply and accept a 0 to 5V analog input. Both parts feature an 8.5Fs successive-approximation ADC, a fast track/hold (1.5Fs), an on-chip clock, and a high-speed 3-wire serial interface.

They digitize signals at a 75ksps throughput rate. An external clock accesses data from the interface, which communicates without external hardware to most digital signal processors and microcontrollers.

The interface is compatible with SPI, QSPIK, and MICROWIREM. MAX187 has an on-chip buffered reference.

Excellent AC characteristics and very low power consumption combined with ease of use and small package size make these converters ideal for remote DSP and sensor applications, or for circuits where power consumption and space are crucial.

Applications include: portable data logging, remote digital signal processing, isolated data aquisition, high-accuracy process control.
