Maxim Integrated MAX1230BEEG T

Description
The MAX1226/MAX1228/MAX1230 are 12-bit analog-to-digital converters (ADCs) with an internal reference, internal temperature sensor, and on-chip FIFO. These devices feature scan mode, internal averaging, and internal clock mode. 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.
