MyMaxim SubscriptionsDescription
The MAX11634–MAX11637 are serial 12-bit analog-to-digital converters (ADCs) with an internal reference and true differential track/hold. 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 MAX11636/MAX11637 have 8 input channels and the MAX11634/ MAX11635 have 4 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 MAX11634–MAX11637 are available in a 16-pin QSOP package. All four devices are specified over the extended -40°C to +85°C temperature range.
