PMC Modules PMC Modules PMC341 Simultaneous A/D Conversion Analog Input PMC341 modules provide fast, high resolution, simultaneous A/D conversion of eight channels. The PMC341 is ideal for high-speed data acquisition. Large memory buffer reduces CPU interactions for increased overall performance. These modules have sixteen analog inputs which are sampled as two eight-channel banks. Eight A/D Specifications Ordering Information converters (ADCs) permit simultaneous conversion of Analog Inputs PMC Modules all eight channels in a bank. All 16 channels share two Input configuration: 16 differential. PMC341 generous 512-sample memory buffers. Conversion of A/D resolution: 14 bits. 14-bit A/D each bank requires only 8µS, and all 16 channels can be Input range: ±10V. PMC341E sampled in just 16µs. Same as PMC341 plus extended temperature range Data sample memory: 512 sample FIFO buffer. Flexible configuration options give you extensive control PMC341R Max. throughput rate: Same as PMC341, except with rear I/O connector over the conversion process. The channels or bank to be Eight channels can be simultaneously acquired. One channel: 125KHz (8µS/conversion) PMC341RE converted, timing, scan mode, and other parameters are 8 channels (same bank): 1MHz (8µS/8 channels) Same as PMC341R plus extended temperature range user-programmable. Interrupt support adds further 16 channels (high & low banks): 1MHz (16µS/16 ch. at control to interrupt upon a programmable threshold Software (see Page 81) maximum 2.2K ohm source resistance). when the memory is full.
