MAX11626–MAX11629/

MAX11632/MAX11633

EVALUATION KIT AVAILABLE

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 six devices operate from either a

+3V supply or a +5V supply, and contain a 10MHz SPI-/

QSPI™-/MICROWIRE®-compatible serial port.

The MAX11626–MAX11629 are available in 16-pin QSOP

packages. The MAX11632/MAX11633 are available in

24-pin QSOP packages. All six devices are specified over

the extended -40°C to +85°C temperature range.
