CORNER GENERAL DESCRIPTION
The ADA4505-1/ADA4505-2/ADA4505-4 are single, dual, and
quad micropower amplifiers featuring rail-to-rail input and output
swings while operating from a single 1.8 V to 5 V power supply
or from dual ±0.9 V to ±2.5 V power supplies. Remote battery-powered sensors, handheld instrumentation
and consumer equipment, hazard detectors (for example, smoke,
fire, and gas), and patient monitors can benefit from the features
of the ADA4505-x amplifiers.
The ADA4505-x family is specified for both the industrial …

quad micropower amplifiers featuring rail-to-rail input and output
swings while operating from a single 1.8 V to 5 V power supply
or from dual ±0.9 V to ±2.5 V power supplies. The ADA4505-x family is specified for both the industrial
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. 4 8 –IN A 2 BALL A1
