NORWOOD, Mass. -- December 19, 2012

Analog Devices, Inc. (ADI) today introduced a high precision amplifier
offering the industry’s best combination of offset voltage, voltage thermal
drift, bandwidth, slew rate and voltage noise for front-end amplifier
circuits. The ADA4077-2 operational amplifier is specifically suited for
applications in process control, chemical and environmental monitoring, motor
control and electronic test and instrumentation due to its high DC precision
with noise, speed and supply current applicable for the designs.

The ADA4077-2 has a typical bandwidth of 3.9 MHz and 7-nV/√Hz voltage noise at
1 kHz while consuming only 400 µA typical at 25°C with ±15-Vdc nominal power
supplies. Available in two grades for offset and thermal drift, the device
provides design engineers with the flexibility to meet budget and packaging
requirements.

Compared to its closest competition, the ADA4077-2 offers higher speed with
lower noise, offset and drift while consuming less power, making the ADA4077-2
an ideal, cost-effective op amp for use in front end sensor interface in
applications such as process control input modules, where high accuracy,
precision, and linearity are critical to accurate measurement of sensor
output.

ADA4077-2 Precision Operational Amplifier Key Features:

  *Low offset voltage: 25µV maximum (B-Grade)
  *Low offset voltage drift: 0.25 µV/°C maximum (B-Grade)
  *Low input bias current: <1.0 nA maximum
  *Input voltage range: V- +1.2 V to V+ -2 V
  *Low noise: 7 nV/√Hz typical
  *Low supply current: 400 µA per amplifier typical
  *Specified for dual voltage supply operation from ±5 V to ±15 V

The ADA4077-2 precision amplifier is well suited to operate with ADI’s 12-,
14- and 16-bit D/A converters and A/D converters up to 1 MSPS, including the
AD5444, AD7265, and AD7266.
