10-Bit 300ksps ADCs with FIFO, Temp Sensor, Internal Reference
Maxim Confidential 
MyMaxim SubscriptionsProduct Details
The MAX1027/MAX1029/MAX1031 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 MAX1031 has 16 input channels, the MAX1029 has 12 input channels, and the MAX1027 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 +3V supply and contain a 10MHz SPI™/QSPI™/MICROWIRE™-compatible serial port.
The MAX1031 is available in 28-pin, 5mm x 5mm, TQFN with exposed pad and 24-pin QSOP packages. The MAX1027/MAX1029 are only available in QSOP packages. All three devices are specified over the extended -40°C to +85°C temperature range.

For 12-bit Applications, please see MAX1227, MAX1229, MAX1231 Description
The MAX1231B/MAX11633/MAX11635 evaluation systems (EV systems) include one master board and one of three daughter boards. The EV systems also include Windows XP®-, Windows Vista®-, and Windows® 7-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the various ADCs. The master board (MAX116XXSPIMB) connects to a PC's USB port and allows the transfer of SPI commands to the corresponding daughter board.
The daughter boards are fully assembled and tested PCBs that demonstrate the capabilities of the MAX1030, MAX1031, MAX1230, MAX1231, MAX11624, MAX11625, MAX11632–MAX11635, MAX11642, and MAX11643 300ksps, 8-/10-/12-bit, 3V/5V, low-power, high-speed SPI ADCs with internal or external references.
Each EV kit daughter board evaluates different ADCs, but only the default ADC referenced in the EV kit daughter board is installed on the board. Contact the factory for free samples of the other pin-compatible ADCs to evaluate these devices or to order individual boards.
