The MAX1226/MAX1228/MAX1230 are serial 12-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 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 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.
