General Description
The MAX1026/MAX1028/MAX1030 are serial 10-bit analog-to-digital converters (ADCs) with an internal reference and an internal temperature sensor. 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 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.
