Analog Devices Inc. AD8216YRZ-RL

Overview

AD8216YRZ-RL from Analog Devices is a high-bandwidth, bidirectional difference amplifier optimized for high-side current sensing in automotive and industrial power systems. It delivers 3 MHz bandwidth, 3 V/V fixed gain, and operates over −4 V to +65 V input common-mode voltage with ±100 ns propagation delay. It is used in diesel-injection controls and H-bridge motor drives where accurate bidirectional shunt voltage amplification under fast-switching conditions is required.

For engineers reviewing the AD8216YRZ-RL datasheet, AD8216YRZ-RL pinout, AD8216YRZ-RL application, or AD8216YRZ-RL equivalent, key selection criteria include its −4 V to +65 V common-mode range, adjustable output offset (0.06 V to 4.9 V), ±4000 V HBM ESD rating, and SOIC-8 packaging qualified for automotive environments up to +125°C.

Technical Context

The AD8216YRZ-RL implements a precision resistor network with laser-trimmed ratios (<0.01% matching) feeding an internal 54 V/V amplifier to achieve a total system gain of exactly 3 V/V. Its input attenuators enable operation with common-mode voltages beyond the supply rail-down to −40 V survival and up to +80 V-while maintaining CMRR ≥80 dB from dc to 20 kHz.

Offset adjustment is implemented via dual reference pins (VREF1/VREF2), supporting ratiometric half-scale biasing, ground-referenced unidirectional output, V+-referenced unidirectional output, or external reference-based bidirectional operation. The device uses a 250 mV internal bias to support negative common-mode inputs without requiring dual supplies.

FAQ

What is the maximum continuous common-mode voltage the AD8216YRZ-RL can handle?

The AD8216YRZ-RL supports a continuous input common-mode voltage range of −4 V to +65 V. Its survival rating extends to −40 V to +80 V, making it suitable for automotive load-dump and inductive-kickback events. This specification is validated across the full −40°C to +125°C operating temperature range and is not dependent on external components or layout.

Can the AD8216YRZ-RL be used for bidirectional current sensing without external components?

Yes, the AD8216YRZ-RL supports true bidirectional current sensing natively. By connecting VREF1 to V+ and VREF2 to GND, the output is set to mid-scale (2.5 V with 5 V supply) ratiometrically-requiring no external resistors, references, or op amps. This configuration enables ±800 mV differential input range with linear response centered at zero current.

Does the AD8216YRZ-RL require a dual supply to operate with negative common-mode voltages?

No, the AD8216YRZ-RL operates from a single 4.5 V to 5.5 V supply and handles common-mode voltages down to −4 V due to its internal 250 mV bias network. This eliminates the need for dual supplies while maintaining accuracy-even when the shunt sits below ground, as in certain solenoid diagnostic configurations.

How does the AD8216YRZ-RL achieve high CMRR despite wide common-mode range?

The AD8216YRZ-RL achieves ≥80 dB CMRR from dc to 20 kHz through laser-trimmed resistor networks (RA, RB, RC, RF) matched to better than 0.01%. This precision trimming compensates for process variation and ensures balanced attenuation of common-mode signals before amplification, preserving rejection performance across temperature and frequency.

Is the AD8216YRZ-RL pin-compatible with other members of the AD8216 family?

Yes, all AD8216 variants-including AD8216YRZ, AD8216YRZ-R7, AD8216WYRZ-RL, and AD8216YRZ-RL-share identical 8-lead SOIC_N (R-8) pinout, electrical specifications, and thermal characteristics. The suffix differences denote packaging (tape-and-reel), automotive qualification (W-grade), and RoHS compliance (Z), not functional or mechanical divergence.
