LF15x, LF25x, LF356B 11 15.1 VCM, High LF35x 10 15.1 Input common-mode VCM VS = ±15 V V voltage range LF15x, LF25x, LF356B −12 –11 VCM, Low LF35x −12 –10 LF15x, LF25x, LF356B 85 100 Common-mode rejection CMRR dB ratio LF35x 80 100 LF15x, LF25x, LF356B 85 100 Supply voltage rejection PSRR dB ratio(4) LF35x 80 100 (4) Supply Voltage Rejection is measured for both supply magnitudes increasing or decreasing simultaneously, in accordance with common practice.
6.8 Power Dissipation Ratings MIN MAX UNIT
LF15x 560 LMC Package (Still Air) LF25x, LF356B, LF35x 400 LF15x 1200 Power Dissipation at LMC Package mW TA = 25°C (1) (2) (400 LF/Min Air Flow) LF25x, LF356B, LF35x 1000 P Package LF25x, LF356B, LF35x 670 D Package LF25x, LF356B, LF35x 380 (1) The maximum power dissipation for these devices must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature, TA. The maximum available power dissipation at any temperature is PD = (TJMAX − TA) / θJA or the 25°C PdMAX, whichever is less. (2) Maximum power dissipation is defined by the package characteristics. Operating the part near the maximum power dissipation may cause the part to operate outside specified limits.
