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.
Employing a new circuit technology, these low cost amplifiers
offer zero input crossover distortion (excellent PSRR and CMRR
performance) and very low bias current, while operating with a
supply current of less than 10 μA per amplifier.
This combination of features makes the ADA4505-x amplifiers
ideal choices for battery-powered applications because they
minimize errors due to power supply voltage variations over the
lifetime of the battery and maintain high CMRR even for a rail-
to-rail op amp.
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
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.

1 Input pins have clamp diodes to the supply pins. Limit input current to 10 mA
or less whenever the input signal exceeds the power supply rail by 0.1 V.
2 Differential input voltage is limited to 5 V or the supply voltage, whichever is less.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

THERMAL RESISTANCE
θJA is specified for the worst-case conditions, that is, a device
soldered in a circuit board for surface-mount packages with its
exposed paddle soldered to a pad (if applicable). Simulated
thermal numbers on a 4-layer (2S/2P) JEDEC standard thermal
test board, unless otherwise specified.
