Highly Integrated Quad 16-Bit, SoftSpan , Voltage Output DAC
for Industrial and Control Applications
TM Design Note 431

Introduction
Digital-to-analog converters (DACs) are prevalent in
industrial control and automated test applications.
General-purpose automated test equipment often requires many channels of precisely controlled voltages
that span several voltage ranges. The LTC2704 is a
highly integrated 16-bit, 4-channel DAC for high-end
applications. It has a wide range of features designed to
increase performance and simplify design.
Unprecedented Integration
The LTC2704 provides true 16-bit performance over six
software selectable ranges: 0V to 5V, 0V to 10V, вЂ“2.5V
to 2.5V, вЂ“5V to 5V, вЂ“10V to 10V and вЂ“2.5V to 7.5V. Four
single-range voltage outputs would normally require
four current-output DACs, two reference ampliп¬Ѓers and
four output ampliп¬ЃersвЂ”seven packages if dual ampliп¬Ѓers are used. Implementing multiple ranges discretely
is prohibitive. Design Note 337 explains the difп¬Ѓculty in
implementing multiple ranges, including the cost of precision-matched resistors and the performance limitations
of analog switches. Control is also complicated, requiring
extra digital lines for each DAC and for range control. The …
