AD8129ARZ-REEL

Instrumentation, Op Amps, Buffer Amps Overview

The AD8129ARZ-REEL is a high-speed differential receiver amplifier manufactured by Analog Devices Inc. It features a gain bandwidth product of 200 MHz and a slew rate of 1060 V/µs at G = +10. The device operates within a supply voltage range of 4.5 V to ±12.6 V, drawing a quiescent current of 10.8 mA. It provides a minimum common-mode rejection ratio (CMRR) of 94 dB from DC to 100 kHz and maintains an input impedance of 1 MΩ differentially. The component is housed in an 8-lead SOIC package and supports an operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• High-speed signal reception with significant bandwidth for twisted-pair transmission
• Excellent common-mode rejection performance across wide frequency ranges
• User-adjustable gain configuration without external components for specific settings
• Integrated power-down functionality for low-power management

Instrumentation, Op Amps, Buffer Amps Applications

• High speed differential line receivers
• Differential-to-single-ended converters
• High speed instrumentation amps
• Level shifting

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the REEL suffix indicates tape-and-reel packaging suitable for automated surface-mount assembly. Confirm the ARZ designation corresponds to the industrial temperature grade (-40°C to +125°C) and lead-free RoHS compliance. Ensure the specific part number matches the required gain characteristics of the AD8129 variant rather than the AD8130.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high CMRR and fast transient response are critical for long cable runs. The AD8129 is optimized for gains of 10 or greater, making it suitable where signal attenuation is significant. Consider the AD8130 if unity gain stability is required instead. Evaluate the 8-lead SOIC thermal dissipation limits against the application's ambient temperature conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the AD8129/AD8130 family of low-cost, high-speed differential receiver amplifiers designed for analog and digital video signals over twisted-pair cables. It serves as a cost-effective alternative to multi-amplifier receiving solutions, offering superior performance metrics while maintaining compatibility with standard driver ICs like the AD8131.
