LTC6240/LTC6241/LTC6242 Single/Dual/Quad 18MHz, Low Noise, Rail-to-Rail Output, CMOS Op Amps DESCRIPTION FEATURES n n n n n n n n n n n n 0.1Hz to 10Hz Noise: 550nVP-P Input Bias Current: 0.2pA (Typ at 25°C) 1pA Max (LTC6240) Low Offset Voltage: 125μV Max Low Offset Drift: 2.5μV/°C Max Gain Bandwidth Product: 18MHz Output Swings Rail-to-Rail Supply Operation: 2.8V to 6V LTC6240/LTC6241/LTC6242 2.8V to ±5.5V LTC6240HV/LTC6241HV/LTC6242HV Low Input Capacitance H-Grade Temperature Range: –40°C to 125°C Single LTC6240 in 5-Pin Low Profile (1mm) ThinSOT™ Package and 8-Pin SO for PCB Guard Ring Dual LTC6241 in 8-Pin SO and Tiny DFN Packages Quad LTC6242 in 16-Pin SSOP and 5mm × 3mm DFN Packages n n n n These op amps have an output stage that swings within 30mV of either supply rail to maximize the signal dynamic range in low supply applications. The input common mode range extends to the negative supply. They are fully specified on 3V and 5V, and an HV version guarantees operation on supplies up to ±5V. The LTC6240 is available in the 8-pin SO and the 5-pin SOT23 packages. The LTC6241 is available in the 8-pin SO, and for compact designs it is packaged in a tiny dual fine pitch leadless (DFN) package. The LTC6242 is available in the 16-pin SSOP as well as the 5mm × 3mm DFN package. APPLICATIONS n The LTC®6240/6241/LTC6242 are single, dual and quad low noise, low offset, rail-to-rail output, unity gain stable CMOS op amps that feature 1pA of input bias current. Input bias current is guaranteed to be 1pA max on the single LTC6240. The 0.1Hz to 10Hz noise of only 550nVP-P, along with an offset of just 125μV are significant improvements over traditional CMOS op amps. Additionally, noise is guaranteed to be less than 10nV/√Hz at 1kHz. An 18MHz gain bandwidth, and 10V/μs slew rate, along with the wide supply range and low input capacitance, make them perfect for use as fast signal processing amplifiers.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: A heat sink may be required to keep the junction temperature below the absolute maximum rating when the output is shorted indefinitely. Note 3: The LTC6240C/LTC6240HVC/LTC6241C/LTC6241HVC, LTC6242C/ LTC6242HVC are guaranteed to meet specified performance from 0°C to 70°C. They are designed, characterized and expected to meet specified performance from –40°C to 85°C, but are not tested or QA sampled at these temperatures. The LTC6240I/LTC6240HVI, LTC6241I/LTC6241HVI, LTC6242I/LTC6242HVI are guaranteed to meet specified performance from –40°C to 85°C. All versions of the LTC6240H/LTC6241H/LTC6242H are guaranteed to meet specified performance from –40°C to 125°C. Note 4: ESD (Electrostatic Discharge) sensitive device. ESD protection devices are used extensively internal to the LTC6240/LTC6241/LTC6242; however, high electrostatic discharge can damage or degrade the device. Use proper ESD handling precautions. Note 5: Matching parameters are the difference between the two amplifiers A and D and between B and C of the LTC6242; between the two amplifiers of the LTC6241. CMRR and PSRR match are defined as follows: CMRR and PSRR are measured in μV/V on the matched amplifiers. The difference is calculated between the matching sides in μV/V. The result is converted to dB. Note 6: This parameter is not 100% tested. Note 7: Bias current at TA = 25°C is 100% tested and guaranteed for the LTC6240 in the S8 package. The LTC6240S5, LTC6241 and LTC6242 are expected to achieve the same performance as the LTC6240S8. All parts are guaranteed to meet specifications over temperature. Note 8: Current noise is calculated from the formula: in = (2qIB)1/2 where q = 1.6 × 10–19 coulomb. The noise of source resistors up to 50GΩ dominates the contribution of current noise. See also Typical Performance Characteristics curve Noise Current vs Frequency. Note 9: Output voltage swings are measured between the output and power supply rails. Note 10: Minimum supply voltage is guaranteed by the power supply rejection ratio test. Note 11: Slew rate is measured in a gain of –2 with RF = 1k and RG = 500Ω. On the LTC6240/LTC6241/LTC6242, VS = ±2.5V, VIN is ±1V and VOUT slew rate is measured between –1V and +1V. On the LTC6240HV/ LTC6241HV/LTC6242HV, VIN is ±2V and VOUT slew rate is measured between –2V and +2V. Note 12: Full-power bandwidth is calculated from the slew rate: FPBW = SR/πVP-P. 624012fe 13 LTC6240/LTC6241/LTC6242 TYPICAL PERFORMANCE CHARACTERISTICS VOS Distribution LTC6241 VOS Temperature
