GENERAL DESCRIPTION
The AD8506 is a dual micro-power amplifier featuring
rail-to-rail input and output swings while operating from
a 1.8 V to 5.5 V single power supply.
Employing a new circuit technology, these low cost amplifiers
offer high linearity (excellent PSRR and CMRR performance)
and very low bias current, while operating with a supply current
of less than 20 μA per amplifier.
This combination of features makes the AD8506 amplifier an
ideal choice for battery-powered applications since it minimizes
errors due to power supply voltage variations over the battery’s
lifetime and maintains relatively high CMRR for a rail-to-rail op
amp.
Remote battery-powered sensors, handheld instrumentation
and consumer equipment, hazard detection (for example, smoke,
fire, and gas), and patient monitors can benefit from the
features of the AD8506 amplifier.
The AD8506 is specified for both the industrial temperature
range (−40°C to +85°C) and the extended industrial temperature
range (−40°C to +125°C). AD8506 dual amplifiers are available
in the standard 8-lead MSOP and WLCSP.
