The OP5340 is one of a range of function modules for the OP5000 FPGA I/O system from Opal-RT Technologies. It allows up to 16 analog signals to be sampled simultaneously through a single module. Given that both the OP5130 External FPGA Processor, and the passive OP5220 carrier can accommodate up to two mezzanine modules, it allows up to 32 signals to be captured per carrier. Several carriers can be connected to a single board slot on an RT-LAB simulator via the OP5110 or OP5120 I/O interface.

The OP5340 features 16 differential channels with individual 16-bit Analog-to-Digital Converters (ADC), which ensures simultaneous signal capture from multiple channels, thus eliminating the skew errors associated with multiplexed channels. Each ADC can sample up to 500 kS/s, giving a total throughput of 8 Ms/s. On-board signal conditioning provides offsets and gains from +/- 100 mV to +/- 16 V as well as over-voltage protection.
