The IVY III Balanced Linestage
Highlights
Functions as either an I/V stage for current-output DACs or linestage for voltage-output DACs
Fully balanced, symmetric operation for ultra-low noise floor
Precision components in differential analog filter stages (2.5% capacitors, 0.1% resistors)
Customizable input impedance to match the application
Balanced and single-ended outputs can be used simultaneously
Ballsie stage is optional and can be left out or simply not powered if not needed
Gain of single-ended outputs can be set independently of balanced outputs to match your application
Designed specifically for our line of DACs
All connections by direct or optional (included) terminal blocks
IVY-III is a balanced active I/V line stage with optional filtering and both balanced and single-ended outputs.
I/V conversion is performed by a pair of Burr-Brown fully-differantial OPA1632 op-amps, and balanced
to single-ended conversion by a National Semiconductor LM4562/LME49720. All op-amps are surface mount (SOIC)
and come pre-installed (unless you note otherwise).
Wima FKP2 polypropylene (MKP) filter capacitors provide low pass filtering in the I/V stage. Each stage has
local Nichicon 100uF KW and Wima 0.1uF MKP2 polypropylene decoupling and bypass capacitors.
IVY-III requires between one (and up to three) ±12-15VDC (bipolar) power supplies. Both our linear LCBPS and
shunt-regulated Placid HD BP will work very well. We recommend
the
Placid HD BP set for ±15VDC for best performance,
powered by a 15V+15V transformer (available
here).
