The MAX11638/MAX11639/MAX11642/MAX11643 are serial 8-bit analog-to-digital converters (ADCs) with an internal reference. These devices feature on-chip FIFO, scan mode, internal clock mode, internal averaging, and AutoShutdown™. The maximum sampling rate is 300ksps using an external clock. The MAX11642/MAX11643 have 16 input channels and the MAX11638/MAX11639 have 8 input channels. These four devices operate from either a +3V supply or a +5V supply, and contain a 10MHz SPI/QSPI™/MICROWIRE®-compatible serial port.

The MAX11638/MAX11639 are available in 16-pin QSOP packages. The MAX11642/MAX11643 are available in 24-pin QSOP packages. All four devices are specified over the extended -40°C to +85°C temperature range.
