ADA4075-2ARZ-R7 Dual Ultra-Low Noise Operational Amplifier
The ADA4075-2ARZ-R7 is a dual-channel, ultra-low noise operational amplifier engineered by Analog Devices (ADI) using its proprietary iPolar® bipolar process, which integrates vertical junction isolation and lateral trench isolation. This advanced technology enables high-performance amplification with minimal die size, delivering exceptional DC and AC characteristics such as a 2.8 nV/√Hz noise density at 1 kHz, 12 V/μs slew rate, and 6.5 MHz gain bandwidth product (GBP). Designed for precision instrumentation and high-fidelity audio applications, the device operates over a wide dual-supply voltage range of ±4.5 V to ±18 V, ensuring flexibility in demanding industrial and consumer environments. Its SOIC-8 package and -40°C to +125°C temperature range make it ideal for compact, high-density designs requiring low power consumption (1.8 mA per channel) and ultra-low distortion (0.0002% typical).
ADA4075-2ARZ-R7 Typical Amplifier Applications
The ADA4075-2ARZ-R7 excels in scenarios demanding low noise, high precision, and compact form factors:
● Professional Audio: High-fidelity preamplifiers, microphone amplifiers, and studio equipment benefit from its ultra-low distortion and noise floor.
● Precision Instrumentation: Data acquisition systems, medical sensors, and test equipment leverage its DC accuracy and thermal stability.
● Active Filters & Signal Conditioning: Low-noise amplification stages in anti-aliasing filters and parametric equalizers ensure clean signal integrity.
● DAC Output Buffers: Differential filtering circuits for high-resolution digital-to-analog converters (DACs) utilize its fast settling time (3,000 ns typical) and low output impedance.
