The MAX1168BCEG+ is a multichannel, 16bit, 200Ksps analogue to digital converter in 24 pin QSOP package. This low power 16bit device feature a successive-approximation ADC, automatic power-down, integrated +4.096V reference and a high-speed SPI/QSPI/MICROWIRE compatible interface, this serial interface simplifies communication with microprocessors (μPs). It operate with a single +5V analogue supply and has a separate digital supply allowing direct interfacing with +2.7V to +5.5V digital logic. The device feature a scan mode that converts each channel sequentially or one channel continuously and it operate in two modes, external reference mode and internal reference mode. The External reference mode has two power modes normal mode and shutdown mode where as internal reference mode offers software programmable, power-down options. A DSPR input and DSPX output allow the device to communicate with digital signal processors (DSPs) with no external glue logic.
