EVALUATION KIT AVAILABLE MAX11626MAX11629/ 12-Bit, 300ksps ADCs MAX11632/MAX11633 with FIFO and Internal Reference General Description Features The MAX11626MAX11629/MAX11632/MAX11633 are Analog Multiplexer with Track/Hold serial 12-bit analog-to-digital converters (ADCs) with an 16 Channels (MAX11632/MAX11633) internal reference. These devices feature on-chip FIFO, 8 Channels (MAX11628/MAX11629) scan mode, internal clock mode, internal averaging, and 4 Channels (MAX11626/MAX11627) AutoShutdown. The maximum sampling rate is 300ksps Single Supply using an external clock. The MAX11632/MAX11633 have 2.7V to 3.6V (MAX11627/MAX11629/MAX11633) 16 input channels the MAX11628/MAX11629 have 8 4.75V to 5.25V input channels and the MAX11626/MAX11627 have 4 (MAX11626/MAX11628/MAX11632) input channels. These six devices operate from either a Internal Reference +3V supply or a +5V supply, and contain a 10MHz SPI-/ 2.5V (MAX11627/MAX11629/MAX11633) QSPI-/MICROWIRE -compatible serial port. 4.096V (MAX11626/MAX11628/MAX11632) The MAX11626MAX11629 are available in 16-pin QSOP External Reference: 1V to V DD packages. The MAX11632/MAX11633 are available in 24-pin QSOP packages. All six devices are specified over 16-Entry First-In/First-Out (FIFO) the extended -40C to +85C temperature range.
