40 Channels of Programmable Industrial Level Output Span Using
the AD5370 16-Bit Voltage Output DAC
Rev. A | Page 1 of 2
CIRCUIT FUNCTION AND BENEFITS
This circuit is a multichannel DAC configuration with
different output spans on groups of channels. It utilizes
the AD5370 to provide 40 DAC channels with 16 bits of
resolution. The AD5370 is configured to have eight channels
with an output span of ±10 V and 24 channels with an output
span of −4 V to +8 V.
The AD5370 is the industry’s only 40-channel DAC offering
these industrial signal level outputs and the flexibility of
multiple output spans with 16-bit resolution. Coupled with the
XFET® series of low noise precision references, the total solution
represents industry-leading DAC channel density, smallest
footprint, flexibility, and performance.
