General Description
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 averag-
ing, 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-compati-
ble 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.
