8 ltc2054/ltc2055 sn20545 20545fas clock feedthrough, input bias current the ltc2054 and ltc2055 use auto-zeroing circuitry to achieve an almost zero dc offset over temperature, common mode voltage, and power supply voltage. the frequency of the clock used for auto-zeroing is typically 1.0khz. the term clock feedthrough is broadly used to indicate visibility of this clock frequency in the op amp output spectrum. there are typically two types of clock feedthrough in auto zeroed op amps like the ltc2054/ ltc2055. the first form of clock feedthrough is caused by the settling of the internal sampling capacitor and is input referred; that is, it is multiplied by the closed loop gain of the op amp. this form of clock feedthrough is independent of the magnitude of the input source resistance or the magnitude of the gain setting resistors. the ltc2054/ ltc2055 have a residue clock feedthrough of less then 0.2 v rms input referred at 1.0khz. the second form of clock feedthrough is caused by the small amount of charge injection occurring during the sampling and holding of the op amp? input offset voltage. the current spikes are multiplied by the impedance seen at the input terminals of the op amp, appearing at the output multiplied by the closed loop gain of the op amp. to reduce this form of clock feedthrough, use smaller valued gain setting resistors and minimize the source resistance at the input. if the resistance seen at the inputs is less than 10k, this form of clock feedthrough is less than the amount of residue clock feedthrough from the first form described above. placing a capacitor across the feedback resistor reduces either form of clock feedthrough by limiting the bandwidth of the closed loop gain. input bias current is defined as the dc current into the input pins of the op amp. the same current spikes that applicatio s i for atio wu uu 0.4 v 10 sec 2054 g16 1 v 1 sec 2054 g17 ltc2054/ltc2055 dc to 1hz noise ltc2054/ltc2055 dc to 10hz noise
9 ltc2054/ltc2055 sn20545 20545fas cause the second form of clock feedthrough described above, when averaged, dominate the dc input bias current of the op amp below 70 c. at temperatures above 70 c, the leakage of the esd protection diodes on the inputs increases the input bias currents of both inputs in the positive direction, while the current caused by the charge injection stays relatively constant. at elevated temperatures (above 70 c) the leakage current begins to dominate and both the negative and positive pins?input bias currents are in the positive direction (into the pins). extended common mode range the ltc2054/ltc2055 input stage is designed to allow nearly rail-to-rail input common mode signals. in addition, signals that extend beyond the allowed input common mode range do not cause output phase inversion. applicatio s i for atio wu uu + 100k ?.5v 2.5v 1k output 3.75v p sine wave ltc2054/55 2054 ta09 500 s/div a v = 1 r l = 100k v s = 2.5v v in = 500hz 7.5v p-p v out = 2v/div v in = 2v/div output input 2054 g19 0v 0v voltage follower with input exceeding the common mode range ltc2054/ltc2055 extended common mode range + 5v 0.1 f 499k 0.1 f 499k 5 1 2 3 4 1 f 5v a v = 100 20545 ta02 10k ? bridge ltc2054hv ?v lt1790-2.5 typical applicatio s u simple differential bridge amplifier
