MAX11626–MAX11629/MAX11632/MAX11633
The MAX11626–MAX11629/MAX11632/MAX11633 are serial 12-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 MAX11632/ MAX11633 have 16 input channels; the MAX11628/ MAX11629 have 8 input channels; and the MAX11626/ MAX11627 have 4 input channels. These eight devices operate from either a +3V supply or a +5V supply, and contain a 10MHz SPI™-/QSPI™-/MICROWIRE™-compatible serial port. The MAX11626–MAX11629 are available in 16-pin QSOP packages. The MAX11632/MAX11633 are available in 24-pin QSOP packages. All eight devices are specified over the extended -40°C to +85°C temperature range.
