10 LTC/LTCHV APPLICATIONS INFORMATION Shutdown The LTC incudes a shutdown pin in the 6-ead SOT- and the SO-8 version. When this active ow pin is high or aowed to foat, the device operates normay. When the shutdown pin is pued ow, the device enters shutdown mode; suppy current drops to μa, a cocking stops, and both inputs and output assume a high impedance state. Cock Feedthrough, Input Bias Current The LTC uses auto-zeroing circuitry to achieve an amost zero DC offset over temperature, common mode votage, and power suppy votage. The frequency of the cock used for auto-zeroing is typicay 7.kHz. The term cock feedthrough is broady used to indicate visibiity of this cock frequency in the op amp output spectrum. There are typicay two types of cock feedthrough in auto zeroed op amps ike the LTC. The first form of cock feedthrough is caused by the setting of the interna samping capacitor and is input referred; that is, it is mutipied by the cosed oop gain of the op amp. This form of cock feedthrough is independent of the magnitude of the input source resistance or the magnitude of the gain setting resistors. The LTC has a residue cock feedthrough of ess then μv RMS input referred at 7.kHz. The second form of cock feedthrough is caused by the sma amount of charge injection occurring during the samping and hoding of the op amp s input offset votage. The current spikes are mutipied by the impedance seen at the input terminas of the op amp, appearing at the output mutipied by the cosed oop gain of the op amp. To reduce this form of cock feedthrough, use smaer vaued gain setting resistors and minimize the source resistance at the input. If the resistance seen at the inputs is ess than k, this form of cock feedthrough is ess than μv RMS input referred at 7.kHz, or ess than the amount of residue cock feedthrough from the first form described above. Pacing a capacitor across the feedback resistor reduces either form of cock feedthrough by imiting the bandwidth of the cosed oop gain. Input bias current is defined as the DC current into the input pins of the op amp. The same current spikes that cause the second form of cock feedthrough described above, when averaged, dominate the DC input bias current of the op amp beow 7 C. At temperatures above 7 C, the eakage of the ESD protection diodes on the inputs increases the input bias currents of both inputs in the positive direction, whie the current caused by the charge injection stays reativey constant. At eevated temperatures (above 8 C) the eakage current begins to dominate and both the negative and positive pin s input bias currents are in the positive direction (into the pins). Input Pins, ESD Sensitivity ESD votages above 7V on the input pins of the op amp wi cause the input bias currents to increase (more DC current into the pins). At these votages, it is possibe to damage the device to a point where the input bias current exceeds the maximums specified in this data sheet. fc
