General Description
The MAX1227/MAX1229/MAX1231 are serial 12-bit ana-
log-to-digital converters (ADCs) with an internal reference
and an internal temperature sensor. These devices fea-
ture an on-chip FIFO, scan mode, internal clock mode,
internal averaging, and AutoShutdown. The maximum
sampling rate is 300ksps using an external clock. The
MAX1231 has 16 input channels, the MAX1229 has 12
input channels, and the MAX1227 has 8 input channels.
All input channels are configurable for single-ended or
differential inputs in unipolar or bipolar mode. All three
devices operate from a +3V supply and contain a 10MHz
SPI-/QSPI-/MICROWIRE-compatible serial port.
The MAX1231 is available in 28-pin 5mm x 5mm TQFN
with exposed pad and 24-pin QSOP packages. The
MAX1227/MAX1229 are only available in QSOP pack-
ages. All three devices are specified over the extended
-40°C to +85°C temperature range.
