Analog Devices Inc. AD8215YRZ

Overview

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

For engineers reviewing the AD8215YRZ datasheet, AD8215YRZ pinout, AD8215YRZ application, or AD8215YRZ equivalent, key selection criteria include its survival voltage (−3 V to +68 V), 120 dB dc CMRR, 450 kHz small-signal bandwidth, ±2.5 mV offset over temperature, and SOIC_N-8 package compatibility with high-voltage PCB layout constraints.

Technical Context

The AD8215YRZ uses a proprietary input stage architecture that maintains linearity across 0 mV–250 mV differential input voltage regardless of common-mode voltage (0 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 features dual-stage output buffering: a high-accuracy gain stage followed by a low-impedance (2 Ω) driver capable of sourcing up to 10 mA and sinking up to 12 mA at 125°C. Input bias current remains below 1 µA across full common-mode and differential ranges, minimizing shunt measurement error.

Key Specifications

Pinout & Package

AD8215YRZ 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 with a beveled corner.

FAQ

What is the maximum common-mode voltage the AD8215YRZ can survive without damage?

The AD8215YRZ has a continuous input voltage survival rating of −3 V to +68 V, meaning it withstands transient overvoltages such as automotive load dump (up to +65 V) and reverse-battery conditions (down to −3 V) without permanent damage. This rating is verified per Absolute Maximum Ratings Table 2 in the Rev. B datasheet and applies regardless of supply voltage or output loading.

Does the AD8215YRZ require external gain-setting resistors or calibration?

No, the AD8215YRZ integrates laser-trimmed precision resistors to deliver a fixed 20 V/V gain with ±0.3% maximum error over −40°C to +125°C. No external resistors, potentiometers, or factory calibration are needed - the gain error specification includes initial tolerance and full-temperature drift, enabling plug-and-play use in production systems.

Can the AD8215YRZ be used for bidirectional current sensing?

No, the AD8215YRZ is designed exclusively for unidirectional current measurement. Its input architecture and output stage are optimized for positive differential inputs (0 mV to 250 mV), and the output voltage range is 0.10 V to 4.90 V at temperature extremes - it does not swing below 0.1 V to represent reverse current flow. For bidirectional sensing, consider the AD8210 or AD8418 families.

What is the minimum differential input voltage the AD8215YRZ can accurately measure?

The AD8215YRZ maintains guaranteed linearity down to 2 mV differential input voltage across its full common-mode range (−2 V to +65 V), as confirmed in Figure 27 and Application Notes section. At 2 mV input, the output is 40 mV - sufficient for detection by most 12-bit ADCs with appropriate gain staging, enabling resolution of sub-100 mA currents with standard shunt values.

Is the AD8215YRZ pin-compatible with other members of the AD821x family?

Yes, the AD8215YRZ shares identical pinout, package (SOIC_N-8), and footprint with AD8210, AD8211, AD8212, and AD8214 - all feature −IN, GND, NC, NC, OUT, V+, NC, +IN arrangement. However, gain, common-mode range, and internal architecture differ; direct substitution requires verification of gain (20 V/V), bandwidth (450 kHz), and CMRR (120 dB) requirements for the target application.
