GBW Gain-Bandwidth Product 0.35 MHz θ M Phase Margin 50 Deg G M Gain Margin 17 dB Amp-to-Amp Isolation (Note 9) 130 dB e n Input-Referred Voltage Noise F = 1 kHz 42 in Input-Referred Current Noise F = 1 kHz 0.0002 Note 1:Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Note 2:Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature and/or multiple Op Amp shorts can result in exceeding the maximum allowed junction temperature of 150˚C. Output currents in excess of±30 mA over long term may adversly affect reliability. Note 3:The maximum power dissipation is a function of TJ(max),θJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(max) −T A)/θJA. Note 4:Human body model, 100 pF discharge through a 1.5 kΩ resistor. Note 5:Typical values represent the most likely parametric norm. Note 6:All limits are guaranteed by testing or correlation. Note 8:V+ = 15V. Connected as Voltage Follower with 10V step input. Number specified is the slower of the positive and negative slew rates. Note 9:Input referred, V+ = 15V and RL = 100 kΩ connected to 7.5V. Each amp excited in turn with 1 kHz to produce VO = 13 VPP . Note 10:For operating at elevated temperatures the device must be derated based on the thermal resistanceθJA with PD = (TJ −T A)/θJA. Note 11:All numbers apply for packages soldered directly into a PC board. Note 12:Do not connect output to V+ when V+ is greater than 13V or reliability may be adversely affected. www.national.com 4

these tasks now fall to the integrator. Note 13:Avoid resistive loads of less than 500Ω , as they may cause instability. FIGURE 1. LMC6024 Circuit Topology (Each Amplifier)

For good CMRR over temperature, low drift resistors should be used. Matching of R3 to R6 and R4 to R7 affects CMRR. Gain may be adjusted through R2. CMRR may be adjusted through R7.
