11 / 16 page 11 LT1055/LT1056 10556fc APPLICATIONS INFORMATION Phase Reversal Protection Most industry standard JFET input op amps (e.g., LF155/ LF156, LF351, LF411, OP15/16) exhibit phase reversal at the output when the negitive common mode limit at the input is exceeded (i.e., from –12V to –15V with ±15V supplies). This can cause lock-up in servo systems. As shown below, the LT1055/LT1056 does not have this problem due to unique phase reversal protection circuitry (Q1 on simplified schematic). 0.5ms/DIV 0.5ms/DIV 0.5ms/DIV LT1055/56 AI06 LT1055/56 AI07 LT1055/56 AI08 TYPICAL APPLICATIONS † Exponential Voltage-to-Frequency Converter for Music Synthesizers INPUT 0V TO 10V LT1055/56 TA03 – + 11.3k* EXPONENT TRIM 2500 Ω* 562 Ω* 3.57k* ZERO TRIM 15V 500k 500 Ω* 4.7k 1.1k 10k* 3k 10k* 1k* 1k* 4.7k 2 3 4 5 6 –15V –15V 7 LT1055 15V 500pF POLYSTYRENE 6 2 3 15V 7 LM301A 15V 6 8 2N3906 2N3904 SAWTOOTH OUTPUT LM329 0.01 µF 1 4 2 3 1 1N148 13 14 15 2.2k 9 7 8 33 Ω TEMPERATURE CONTROL LOOP SCALE FACTOR 1V IN OCTAVE OUT *1% METAL FILM RESISTOR PIN NUMBERED TRANSISTORS = CA3096 ARRAY – + †For ten additional applications utilizing the LT1055 and LT1056, please see the LTC1043 data sheet and Application Note 3.
