Package
MAX1226/MAX1228/MAX1230
The MAX1226/MAX1228/MAX1230 are serial 12-bit ana-
log-to-digital converters (ADCs) with an internal reference
and an internal temperature sensor. These devices fea-
ture on-chip FIFO, scan mode, internal clock mode, inter-
nal averaging, and AutoShutdown™. The maximum
sampling rate is 300ksps using an external clock. The
MAX1230 has 16 input channels, the MAX1228 has 12
input channels, and the MAX1226 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 +5V supply and contain a 10MHz
SPI™/QSPI™/MICROWIRE™-compatible serial port.
The MAX1230 is available in 28-pin 5mm x 5mm thin
QFN with exposed pad and 24-pin QSOP packages.
The MAX1226/MAX1228 are only available in QSOP
packages. All three devices are specified over the
extended -40°C to +85°C temperature range.
