DNR-AO-308-350

DNR-AO-308-350
8-Channel, 16-bit, 100 kS/s per channel, ±10V High-Current Analog Output Board for the PowerDNR RACKtangle
 
The DNR-AO-308-350 is a high-precision, true 16-bit, 8-channel high-current analog output board for use with popular RACKtangle® I/O chassis. The board offers per-channel digital offset and gain calibration, buffered output, excellent linearity, and low output noise. The DNR-AO-308-350 features current boosters that allows a maximum output current of ±50mA per channel and provides sense lines for better accuracy. The board is and ideal solution in high-accuracy data acquisition and control applications where current drive requirements exceed the more typical analog output ratings of ±5mA or ±10mA per channel. For best accuracy all available ground lines should be tied together.

The DNR-AO-308-350 is fully supported by the UEIDaq Framework Data Acquisition Software Library for Windows. Linux and QNX drivers available.
