3 Digit LCD/LED Display A/D
Converters
True differential
inputs and reference are useful in all systems, but give the
desiger an uncommon advantage when measuring load
cells, strain gauges and other bridge type transducers.
Finally, the true economy of single power supply operation
(WS7106), enables a high performance panel meter to built
with the addition of only 10 passive compoents and a disply.
• True Differential Input and Reference, Direct Display
Drive
• On Chip Clock and Reference
• No Additional Active Circuits Required
Guaranteed Zero Reading for 0V Input on All Scales
True Polarity at Zero for Precise Null Detection
