General Description
The MAX1026/MAX1028/MAX1030 are serial 10-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
MAX1030 has 16 input channels, the MAX1028 has 12
input channels, and the MAX1026 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 MAX1030 is available in 28-pin 5mm x 5mm TQFN
with exposed pad and 24-pin QSOP packages. The
MAX1026/MAX1028 are only available in QSOP pack-
ages. All three devices are specified over the extended
-40°C to +85°C temperature range.
