THE LT1007 IS CAPABLE OF PROVIDING EXCITATION CURRENT
DIRECTLY TO BIAS THE 350Ω BRIDGE AT 5V. WITH ONLY 5V ACROSS
THE BRIDGE (AS OPPOSED TO THE USUAL 10V) TOTAL POWER
DISSIPATION AND BRIDGE WARM-UP DRIFT IS REDUCED. THE BRIDGE
OUTPUT SIGNAL IS HALVED, BUT THE LT1007 CAN AMPLIFY THE
REDUCED SIGNAL ACCURATELY.
