Description
The MAX11618–MAX11621/MAX11624/MAX11625 are serial 10-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 MAX11624/MAX11625 have 16 input channels, the MAX11620/MAX11621 have 8 input channels, and the MAX11618/MAX11619 have 4 input channels. These six devices operate from either a +3V supply or a +5V supply, and contain a 10MHz SPI™-/QSPI™-/MICROWIRE™-compatible serial port.
The MAX11618–MAX11621 are available in 16-pin QSOP packages. The MAX11624/MAX11625 are available in 24-pin QSOP packages. All six devices are specified over the extended -40°C to +85°C temperature range.
