The MAX125CCAX+D is a 2 x 4-channel, simultaneous sampling 14bit data acquisition system (DAS) in 36 pin SSOP package. This use a successive-approximation conversion technique and four simultaneous-sampling track/hold (T/H) amplifiers to convert analogue signals into 14bit digital outputs. Each T/H has two multiplexed inputs allowing a total of eight inputs. Each T/H output is converted and stored in memory to be accessed sequentially by the parallel interface with successive read cycles. The parallel interface's data access and bus-release timing specifications are compatible with most popular digital signal processors and 16bit/32bit microprocessors, so the device conversion results can be accessed without resorting to wait states. It is used in vibration, waveform analysis and power grid synchronization.
