摘要：
High performance instruments are demanded in today's exploration and research. In a multichannel seismic recording system, high sampling rate and wide dynamic range are highlighted, The design given here uses two analog digital converters (ADC) incorporating with one digital analog converter (DAC) connected as a divider to obtain 24-bit resolution. In addition, two sample/hold amplifiers are configured as a pipelined system to make the two ADCs function parallely. The timing diagram is presented.
