The ADA4841-2YRZ-RL is a dual low power, low noise, rail-to-rail output operational amplifier (op-amp) from Analog Devices Inc. It is unity gain stable and has a quiescent current of 1.5 mA maximum. The ADA4841-2YRZ-RL offers excellent performance for a wide range of applications, including:

• Portable instrumentation
• High channel count data acquisition systems
• Industrial measurement systems
• Medical devices
• Audio and video processing systems

The ADA4841-2YRZ-RL features low wideband voltage noise (2.1 nV/√Hz) and current noise (1.4 pA/√Hz), as well as excellent spurious-free dynamic range (SFDR) of −105 dBc at 100 kHz. It also has low 1/f noise (7 nV/√Hz and 13 pA/√Hz at 10 Hz), which makes it ideal for applications where low noise performance at low frequencies is critical.

The ADA4841-2YRZ-RL can swing its output to within 50 mV of either rail, making it ideal for driving capacitive loads. It can also drive up to 10 pF of capacitive load with minimal peaking.

The ADA4841-2YRZ-RL is available in a leadless 8-pin SOIC package. It is RoHS compliant and rated to operate over the industrial temperature range (−40°C to +125°C).
