PCI Boards PCI Boards APC341 Simultaneous A/D Conversion Analog Input APC341 boards provide fast, high resolution, simultaneous A/D conversion of eight channels. This board is ideal for high-speed data acquisition. A large memory buffer reduces CPU interactions for increased overall performance. These boards have sixteen analog inputs which are sampled as two eight-channel banks. Eight PCI Bus Compliance Specifications This device meets or exceeds all written PCI local bus A/D converters (ADCs) permit simultaneous Analog Inputs specifications per rev. 2.2 dated December 1998. conversion of all eight channels in a bank. All Input configuration: 16 differential channels. System base address: This board operates in memory space. It 16 channels share two generous 512-sample A/D resolution: 14 bits. consumes 4K of memory space. memory buffers. Conversion of each bank requires Input range: ±10V. Data transfer bus: Slave with 32, 16, and 8-bit data transfer only 8µS, and all 16 channels can be sampled in operation. Maximum throughput rate: just 16µs. Eight channels can be simultaneously acquired. Interrupts (INTA#): Interrupt A is used to request an interrupt. One channel: 125KHz (8µS/conversion) Flexible configuration options give you extensive control 8 channels (same bank): 1MHz (8µS/8 channels) over the conversion process. The channels or bank to be Ordering Information 16 channels (high & low banks): 1MHz (16µS/16 ch. at converted, timing, scan mode, and other parameters are maximum 2.2K ohm source resistance). I/O Boards user-programmable. Interrupt support adds further Data sample memory: Two 512-sample memory buffers. APC341 control to interrupt upon a programmable threshold Analog input board A/D triggers: Internal timer, external, and software. when the data in memory exceeds the set threshold.
