For combination of steps accuracy is additive. 2. Thru-loss is minimum insertion loss with all attenuation elements bypassed (All TTL controls state are Low) 3. For optimum operation of TOAT models, ensure the device case is properly connected to the ground plane (of PC board) Outline Drawing Additional Specifications DC Voltage +5V DC Current 12mA max.
