Product Details

The MAX11618–MAX11621/MAX11624/MAX11625 are serial 10-bit analog-to-digital converters (ADCs) with an internal reference. 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 MAX11624/MAX11625 have 16 input channels, the MAX11620/MAX11621 have 8 input channels, and the MAX11618/MAX11619 have 4 input channels. These six devices operate from either a +3V supply or a +5V supply, and contain a 10MHz SPI™-/QSPI™-/MICROWIRE™-compatible serial port.

The MAX11618–MAX11621 are available in 16-pin QSOP packages. The MAX11624/MAX11625 are available in 24-pin QSOP packages. All six devices are specified over the extended -40°C to +85°C temperature range.

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.
