7.5V 5k 2.5V 3 7 + 6 LT1007 LT1009 2 – 4 –7.5V REFERENCE OUT 350Ω 15V BRIDGE 3 + 7 6 OUTPUT LT1007 301k* 0V TO 10V ZERO 2 – TRIM 4 1µF 301k* 10k 7.5V –15V GAIN 2 – 7 TRIM 499Ω* 6 50k LT1007 *RN60C FILM RESISTOR 3 + THE LT1007 IS CAPABLE OF PROVIDING EXCITATION CURRENT 4 DIRECTLY TO BIAS THE 350Ω BRIDGE AT 5V. WITH ONLY 5V ACROSS THE BRIDGE (AS OPPOSED TO THE USUAL 10V) TOTAL POWER –7.5V DISSIPATION AND BRIDGE WARM-UP DRIFT IS REDUCED. THE BRIDGE OUTPUT SIGNAL IS HALVED, BUT THE LT1007 CAN AMPLIFY THE REDUCED SIGNAL ACCURATELY. 1007/37 TA09
