What Is the PGA309AIPWT Rated Power Dissipation specified, not on any datasheet? What is the proper way to calculate power and max allowable power.
Hello Bruce,
Please see this TI Precision Labs: Op Amps - Power and Temperature training video for a full discussion on how to calculate power dissipation and temperature for a variety of amplifier products.
At DC, which is how the PGA309 is typically operated, the maximum power dissipation of an amplifier is equal to:
Pdc_max = (Vcc^2)/(4*R_L), where Vcc is the power supply voltage and R_L is the total effective load resistance.
