Analog Devices Inc. AD8215YRZ-RL

Overview

AD8215YRZ-RL from Analog Devices is a high-voltage, unidirectional current shunt monitor with fixed 20 V/V gain, ±0.3% total gain error over −40°C to +125°C, −2 V to +65 V common-mode input range, and buffered rail-to-rail output. It enables precision high-side current sensing in automotive engine management and industrial motor controls using a 5 V supply.

For engineers reviewing the AD8215YRZ-RL datasheet, AD8215YRZ-RL pinout, AD8215YRZ-RL application, or AD8215YRZ-RL equivalent, key selection criteria include its guaranteed 120 dB dc CMRR, 6 µV/°C typical offset drift, 450 kHz small-signal bandwidth, and SOIC_N-8 package compatibility with high-voltage industrial and AEC-Q100–qualified automotive systems.

Technical Context

The AD8215YRZ-RL employs proprietary input-stage circuitry to maintain linearity across 0 mV to 250 mV differential input voltage regardless of common-mode voltage (−2 V to +65 V). Its gain-setting resistors are laser-trimmed to 0.01% matching, enabling stable 20 V/V amplification without external calibration.

It delivers ground-referenced output directly compatible with standard 5 V ADCs, supports indefinite output short-circuit duration, and features −8 ppm/°C typical gain drift and 70 nV/√Hz input-referred noise at 1 kHz - all while operating from a single 4.5 V to 5.5 V supply.

Key Specifications

Pinout & Package

AD8215YRZ-RL is housed in an 8-lead SOIC_N (narrow-body) package per JEDEC MS-012-AA, with 1.27 mm lead pitch and 5.00 mm × 4.00 mm body dimensions. Pin 1 is marked by a beveled corner.

FAQ

What is the common-mode input voltage range of the AD8215YRZ-RL?

The AD8215YRZ-RL supports a continuous common-mode input voltage range of −2 V to +65 V, with survival capability up to −3 V and +68 V. This allows direct connection to battery rails and high-side switch nodes in automotive and industrial systems without level-shifting circuitry. The AD8215YRZ-RL maintains specified performance across this full range, including 120 dB CMRR at dc when V_CM > 5 V.

Does the AD8215YRZ-RL require external gain-setting resistors?

No, the AD8215YRZ-RL has a fixed, factory-trimmed gain of 20 V/V achieved via laser-trimmed internal resistors matched to within 0.01%. This eliminates external components, reduces board space, and guarantees ±0.3% maximum gain error over −40°C to +125°C - a key advantage over programmable current sense amplifiers requiring precision external resistors.

Can the AD8215YRZ-RL be used for low-side current sensing?

Yes, the AD8215YRZ-RL supports low-side current sensing configurations. Its high common-mode rejection (>90 dB up to 40 kHz when V_CM < 5 V) and ground-referenced output make it suitable for shunt placement between load and ground. However, its primary design emphasis is high-side sensing; for dedicated low-side applications with ultra-low offset, alternatives like the AD8210 may offer tighter specifications.

What is the output voltage range of the AD8215YRZ-RL at full temperature range?

The AD8215YRZ-RL delivers an output voltage range of 0.10 V to 4.90 V over −40°C to +125°C when powered from a 5 V supply. At room temperature, the range extends to 0.03 V to 4.95 V. This rail-to-rail buffered output interfaces directly with standard 5 V ADCs without external level-shifting or amplification, preserving dynamic range and simplifying signal chain design.

Is the AD8215YRZ-RL qualified for automotive applications?

The AD8215YRZ-RL itself is not AEC-Q100 qualified; however, it shares identical die and SOIC_N-8 packaging with the automotive-grade AD8215WYRZ-RL. Analog Devices explicitly states that only W-suffix variants are controlled for automotive reliability. For production automotive use, designers must select AD8215WYRZ-RL or AD8215WYRZ-R7 - the AD8215YRZ-RL is intended for industrial and prototyping applications where full automotive qualification is not required.
