General Description
The MAX11638/MAX11639/MAX11642/MAX11643 are
serial 8-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 MAX11642/
MAX11643 have 16 input channels and the MAX11638/
MAX11639 have 8 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 MAX11638/MAX11639 are available in 16-pin
QSOP packages. The MAX11642/MAX11643 are avail-
able in 24-pin QSOP packages. All four devices are
specified over the extended -40°C to +85°C tempera-
ture range.
