4 / 10 page TS613 4/10 THERMAL INFORMATION The TS613 is housed in an Exposed-Pad plastic package. As described on the figures below, this package uses a leadframe upon which the dice is mounted. This leadframe is exposed as a thermal pad on the underside of the package. The thermal contact is direct with the dice. This thermal path provide an excellent thermal performance. The thermal pad is electrically isolated from all pins in the package. It can also be soldered to a copper area of the PCB underneath the package. Through these thermal paths within this copper ar- ea, heat can be conducted away from the pack- age. In this case, the copper area must be con- nected to (-Vcc) INTERMODULATION DISTORTION The curves shown below are the measurements results of a single operator wired as an adder with a gain of 15dB. The operational amplifier is supplied by a symmet- ric ±6V and is loaded with 25Ω. Two synthesizers (Rhode & Schwartz SME) gen- erate two frequencies (tones) (70 & 80kHz ; 180 & 280kHz). An HP3585 spectrum analyzer measures the spu- rious level at different frequencies. The curves are traced for different output levels (the value in the X ax is the value of each tone). The output levels of the two tones are the same. The generators and spectrum analyzer are phase locked to enhance measurement precision. 3rd ORDER INTERMODULATION Gain=15dB, Vcc= ±6V, RL=25 Ω, 2 tones 70kHz/ 80kHz 2nd ORDER INTERMODULATION Gain=15dB, Vcc= ±6V, RL=25 Ω, 2 tones 180kHz/ 280kHz, Spurious measurement @100kHz 3rd ORDER INTERMODULATION Gain=15dB, Vcc= ±6V, RL=25 Ω, 2 tones 180kHz/ 280kHz Cross Section View DICE Bottom View Side View 1 1,5 2 2,5 3 3,5 4 4,5 -100 -90 -80 -70 -60 -50 -40 -30 -20 -10 0 Vout peak (V) 230kHz 220kHz 90kHz 60kHz Vout peak (V) 1,5 2 2,5 3 3,5 4 4,5 -70 -65 -60 -55 1 1,522,533,5 4 4,5 -100 -90 -80 -70 -60 -50 -40 -30 -20 -10 0 Vout peak (V) 80kHz 640kHz 380kHz 740kHz |
