OUTPUT RANGES
The LTC2704 is a quad DAC with software-programmable
output ranges. SoftSpan provides two unipolar output
ranges (0V to 5V and 0V to 10V), and four bipolar ranges
(±2.5V, ±5V, ±10V and – 2.5V to 7.5V). These ranges are
obtained when an external precision 5V reference and
analog supplies of ±12V to ±15V are used. When a refer-
ence voltage of 2V and analog supplies of ±5V are used,
the SoftSpan ranges become: 0V to 2V, 0V to 4V, ±1V, ±2V,
±4V and –1V to 3V. The output ranges are linearly scaled
for references other than 2V and 5V (appropriate analog
supplies should be used within the range ±5V to ±15V).
Each of the four DACs can be programmed to any one of
the six output ranges. DAC outputs can swing to ±10V
on ±10.8V supplies (±12V supplies with ±10% tolerance)
while sourcing or sinking 5mA of load current.
