Bias is nominally Vd1=Vd2=5V, ITOTAL=105mA. Additionally there are six total source resistors on chip. The three resistors on the input stage are 16.6, 29.0 and 29.0 Ohms. The three resistors on the output stage are 12.5, 12.5 and 9.0 Ohms. One of these must be bonded to ground for each amplifier stage to achieve performance as shown. Bonding to one of the other resistors or any or all in parallel may allow additional performance adjustment. Lastly for additional stability pad #3 can be grounded instead of bond pad #2. App Note [2] Bias Arrangement - Each DC pad (Vd) needs to have DC bypass capacitance (~100-200 pF) as close to the device as possible. Additional DC bypass capacitance (~0.01 uF) is also recommended. MTTF Table (TBD) (Thermal Resistance (Rth) is 60.0ºC/W) These numbers were calculated based on accelerated life test information and thermal model analysis received from the fabricating foundry.
