THE LT1124/LT1125 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 LT1124/LT1125 CAN
AMPLIFY THE REDUCED SIGNAL ACCURATELY.
