AD8656ARMZ Rail-to-Rail Amplifier 28 MHz Bandwidth Op-Amp
The AD8656ARMZ is a low-noise, precision CMOS dual operational amplifier from Analog Devices, designed for high-performance signal processing applications. It features industry-leading noise performance (2.7 nV/√Hz at 10 kHz) and ultra-low distortion (THD+N of 0.0007%), making it ideal for precision analog circuits. The amplifier supports rail-to-rail input and output operation, enabling full dynamic range in single-supply systems (2.7V to 5.5V). With a bandwidth of 28 MHz and a slew rate of 11 V/µs, it excels in high-speed applications while maintaining excellent DC accuracy through ADI’s proprietary DigiTrim® technology. The device operates across an industrial temperature range (-40°C to +125°C) and is available in an 8-pin MSOP package, suitable for space-constrained designs.
Applications
● Data Acquisition Systems: Buffering ADCs/DACs for high-resolution signal conversion.
● Audio Processing: Microphone preamplifiers and mixers benefit from its low noise and distortion.
● Industrial Control & Instrumentation: Enhances accuracy in sensor interfaces and process control loops.
● Automotive Electronics: Suitable for collision avoidance and other high-reliability systems.
● PLL Filters & Precision Filters: Ensures stable frequency synthesis and signal conditioning.
CMOS Amplifier Alternative Models
For design flexibility, consider these alternatives:
1. AD8656ARZ-REEL: SOIC-8 package, similar specs, lead-free compliance.
2. AD8656WARMZ-REEL: AEC-Q100 qualified for automotive use, MSOP-8.
3. GM4500 (by Comemotech): 5V CMOS alternative with comparable noise and precision.
4. LMV797MM/NOPB (TI): 17 MHz GBP, lower cost but reduced performance.
