Analog Devices Inc. AD8216YRZ-R7

Overview

AD8216YRZ-R7 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, ±4 V to +65 V input common-mode range, and <100 ns propagation delay-enabling accurate real-time monitoring of rapidly changing load currents in DC-DC converters and motor controls.

For engineers reviewing the AD8216YRZ-R7 datasheet, AD8216YRZ-R7 pinout, AD8216YRZ-R7 application, or AD8216YRZ-R7 equivalent, key selection criteria include its adjustable output offset (0.06 V to 4.9 V), ±10 µV/°C offset drift, −40°C to +125°C automotive-grade temperature range, and SOIC_N-8 package compatibility with high-voltage shunt-based current measurement topologies.

Technical Context

The AD8216YRZ-R7 implements a precision resistor-trimmed attenuator network (laser-trimmed to 0.01% ratio matching) feeding a 54 V/V internal amplifier to achieve a total system gain of exactly 3 V/V. Its input stage operates with 200 kΩ common-mode and 400 kΩ differential impedance, enabling stable amplification even when inputs exceed supply rails by up to 60 V.

Output offset is fully configurable via dual reference pins (VREF1/VREF2): tied to GND for unidirectional ground-referenced output, to V+ for V+-referenced mode, or split across V+/GND for ratiometric mid-scale biasing-supporting bidirectional current detection without external references.

FAQ

What is the maximum continuous common-mode voltage the AD8216YRZ-R7 can withstand?

The AD8216YRZ-R7 supports a continuous input common-mode voltage range of −4 V to +65 V under normal operation. Its absolute maximum rating extends to −40 V to +80 V for survival conditions, making it suitable for 42 V automotive battery systems with load-dump transients. This specification is validated across the full −40°C to +125°C temperature range and applies directly to the AD8216YRZ-R7 device in its SOIC_N-8 package.

How does the AD8216YRZ-R7 achieve bidirectional current sensing capability?

The AD8216YRZ-R7 achieves bidirectional current sensing through its dual reference input pins (VREF1 and VREF2), which allow the output DC offset to be precisely set anywhere from 0.06 V to 4.9 V with a 5 V supply. When both pins are biased at 2.5 V-typically by connecting VREF1 to V+ and VREF2 to GND-the output rests at mid-scale (2.5 V), enabling symmetric ±800 mV differential input detection. This configuration is explicitly documented for the AD8216YRZ-R7 in the "Bidirectional Operation" section of its Rev. C datasheet.

What is the guaranteed offset drift specification for the AD8216YRZ-R7 over temperature?

The AD8216YRZ-R7 guarantees an offset drift of ±10 µV/°C maximum across its specified operating temperature range of −40°C to +125°C. This parameter is measured as RTI (referred-to-input) and is confirmed in Table 1 of the official Rev. C datasheet under "Offset Drift." The value reflects worst-case variation across production units and ensures minimal measurement error drift in under-hood automotive applications where ambient temperatures fluctuate widely.

Can the AD8216YRZ-R7 operate with a supply voltage other than 5 V?

Yes, the AD8216YRZ-R7 operates with a supply voltage range of 4.5 V to 5.5 V, as specified in the "Power Supply" section of its datasheet. While 5 V is the typical supply, the device maintains full performance-including gain accuracy, bandwidth, and output range-across this window. Supply rejection ratio is 70 dB, meaning output offset remains stable even with minor rail variations, a feature validated for the AD8216YRZ-R7 in automotive environments with noisy battery supplies.

Is the AD8216YRZ-R7 pin-compatible with other members of the AD8216 family?

Yes, the AD8216YRZ-R7 shares identical pinout, electrical characteristics, and package (SOIC_N-8, R-8) with all other AD8216 variants including AD8216YRZ, AD8216WYRZ-R7, and AD8216WYRZ-RL. Differences are limited to packaging format (tape-and-reel vs. tube), automotive qualification (W-grade), and RoHS compliance (Z suffix)-all of which preserve mechanical and electrical interoperability. This pin compatibility is confirmed in the "Ordering Guide" on page 14 of the AD8216 Rev. C datasheet.
