LTC2054/LTC2055 Single/Dual Micropower Zero-Drift Operational Amplifiers DESCRIPTIO The LTC®2054/LTC2055 are low power, low noise single/ dual zero-drift operational amplifiers available in the SOT-23 (ThinSOTTM) and MS8 packages. For space limited applications, the LTC2055 is also available in a 3mm × 3mm × 0.8mm dual fine pitch leadless package (DFN). They operate from a single 2.7V minimum supply and support ± 5V applications. The current consumption is typically 150µA for the LTC2054 and 130µA/amp for the LTC2055. The LTC2054/LTC2055, despite their miniature size, feature uncompromising DC performance. The typical input offset voltage and offset drift are 0.5µV and 25nV/°C. The almost zero DC offset and drift are supported with a power supply rejection ratio (PSRR) and common mode rejection ratio (CMRR) of more than 130dB. The input common mode voltage ranges from the negative supply up to typically 0.5V from the positive supply. The open-loop gain is typically 140dB. The LTC2054/LTC2055 also feature a 1.6µVP-P DC to 10Hz noise and a 500kHz gain-bandwidth product. , LTC and LT are registered trademarks of Linear Technology Corporation.

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 0.2µVRMS input referred at 1.0kHz. LTC2054/LTC2055 DC to 1Hz Noise 0.4µV 10 SEC LTC2054/LTC2055 DC to 10Hz Noise 1µV 1 SEC sn20545 20545fas 8 U 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’s 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 2054 G16 2054 G17 W UU LTC2054/LTC2055 APPLICATIO S I FOR ATIO 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). INPUT VIN = 2V/DIV 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.
