12-Bit, 300ksps ADCs
with FIFO and Internal Reference
General Description
The MAX11626–MAX11629/MAX11632/MAX11633 are
serial 12-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 MAX11632/
MAX11633 have 16 input channels; the MAX11628/
MAX11629 have 8 input channels; and the MAX11626/
MAX11627 have 4 input channels. These eight devices
operate from either a +3V supply or a +5V supply, and
contain a 10MHz SPI™-/QSPI™-/MICROWIRE™-com-
patible serial port.
The MAX11626–MAX11629 are available in 16-pin
QSOP packages. The MAX11632/MAX11633 are avail-
able in 24-pin QSOP packages. All eight devices are
specified over the extended -40°C to +85°C tempera-
ture range.
