41 07 07 The ADA4505-x family is specified for both the industrial Figure 5. 14-Lead TSSOP (RU-14) Figure 6. 14-Ball WLCSP (CB-14-1) temperature range (−40°C to +85°C) and the extended industrial temperature range (−40°C to +125°C). The ADA4505-1 single amplifier is available in a tiny 5-lead SOT-23 and a 6-ball WLCSP. The ADA4505-2 dual amplifier is available in a standard 8-lead MSOP and a 8-ball WLCSP. The ADA4505-4 quad amplifier is available in a 14-lead TSSOP and a 14-ball WLCSP. The ADA4505-x family is a member of a growing series of zero crossover op amps offered by Analog Devices, Inc., including the AD8505/AD8506/AD8508, which also operate from a single 1.8 V to 5 V power supply or from dual ±0.9 V to ±2.5 V power supplies.
