AD210ATI 3-Port Isolation Amplifier — Description

The AD210ATI is the latest addition to a new generation of affordable, high-performance isolation amplifiers. This three-port, wide-bandwidth amplifier is built using surfacemounted components in an automated assembly process. By combining advanced design expertise with cutting-edge manufacturing technology, the AD210ATI delivers a highly compact, cost-effective isolator with performance and user features that far exceed those of more expensive alternatives.
The AD210ATI provides complete isolation, with both signal and power isolation achieved through internal transformer coupling. Its fully integrated design, powered by a single +15V supply, eliminates the need for an external DC/DC converter, a common requirement for optically coupled isolation devices. The true three-port design allows the AD210 to function as both an input and output isolator, making it ideal for single or multi-channel applications. It maintains superior performance even under sustained common-mode stress.
Offering high accuracy and full galvanic isolation, the AD210 effectively breaks ground loops and leakage paths, while rejecting common-mode voltage and noise that could otherwise compromise measurement accuracy. Additionally, the AD210 provides robust protection against fault conditions that could potentially damage other components in a measurement system.

AD210ATI vs. the Original AD210

The AD210AN, AD210BN and AD210JN are out of production. The AD210ATI is a pin-compatible drop-in replacement that improves every dynamic specification while lowering quiescent current — and ATI guarantees production for ≥10 years.

02 / Engineering rationale

Why Engineers Choose the AD210ATI Isolation Amplifier

Every figure below is taken directly from the AD210ATI datasheet specification table.

High common-mode performance

2500V rms continuous and ±3500V peak continuous between any two ports (AD210JNATI: 1500V rms, ±2000V peak). A 5pF common-mode input capacitance yields 120dB CMR at G = 100V/V and 2μA rms max leakage at 240V rms, 60Hz.

Precision DC accuracy

±0.005% max nonlinearity (B grade), ±25ppm/°C max gain drift over 0°C to +70°C, and (±10 ±30/G) μV/°C input offset drift — low-level sensor signals survive the trip across the barrier.

Bandwidth to close a control loop

500kHz full-power bandwidth at G = 1V/V (300kHz at G = 100V/V), 10V/μs slew rate and 1μs rise time. That leaves ample margin in control loops, where limited bandwidth could otherwise lead to instability.

True three-port isolation

Input, output and power ports are mutually independent, so one part serves as either an input or an output isolator, and the system stays protected if the power source faults.

Isolated power included

±15V at ±5mA is available at both the input and output sections, from a single +15V supply — enough to run floating signal conditioners, front-end amplifiers or remote transducers with no external DC/DC converter.

Uncommitted input amplifier

The input op amp is left free for buffering, gain (1V/V to 100V/V) or custom signal conditioning. Linear differential input range is ±10V; output is ±10V min into 2kΩ.

Board-friendly DIP package

1.00" × 2.10" × 0.350" (25.4 × 53.3 × 8.9 mm), low enough for 0.5" card racks, with pin spacing chosen to preserve isolation clearance between ports.

Industrial temperature range

Rated performance from −25°C to +85°C; operating and storage range −40°C to +85°C.

03 / Selection

Choosing the Right AD210ATI Grade

All three grades share 500kHz bandwidth, 1μs rise time, 30mA quiescent current, ±10V input and output range, and a DIP package.

AD210BNATI

Nonlinearity ±0.005% max
Gain error ±1% max
CMV 2500V rms / ±3500V peak

Highest accuracy. Precision instrumentation, calibration-grade measurement, low-level bridge and shunt signals.

AD210ANATI

Nonlinearity ±0.015% max
Gain error ±2% max
CMV 2500V rms / ±3500V peak

The general-purpose choice for industrial process signal isolation and multichannel data acquisition.

AD210JNATI

Nonlinearity ±0.015% max
Gain error ±2% max
CMV 1500V rms / ±2000V peak

Same speed and accuracy as the AN grade at a lower isolation rating — for cost-sensitive designs.

04 / FAQ

AD210ATI Isolation Amplifier — Frequently Asked Questions

Tap a question to expand.

Is the AD210ATI a true drop-in replacement for the AD210?

Yes. The AD210ATI keeps the AD210 pinout and the same 1.00" × 2.10" × 0.350" DIP footprint, so an existing board needs no layout change. Every specification is equal to or better than the original part.

What supply does the AD210ATI need?

A single +15V supply at the power port — 15V ±5% for rated performance, 15V ±10% operating. Quiescent current is 30mA; full load with full signal draws 80mA. The isolated ±15V rails for the input and output sections are generated internally from a 2.5MHz carrier, so no external DC/DC converter is required.

How much common-mode voltage can the AD210ATI withstand?

2500V rms continuous at 60Hz and ±3500V peak DC continuous, input-to-output, for the AD210ANATI and AD210BNATI. The AD210JNATI is rated 1500V rms and ±2000V peak. Leakage current is 2μA rms max at 240V rms, 60Hz.

What gain range does the AD210ATI support?

1V/V to 100V/V, set through the uncommitted input amplifier. Bandwidth is 500kHz at G = 1V/V and 300kHz at G = 100V/V; common-mode rejection reaches 120dB at G = 100V/V.

AD210ATI or AD215ATI — which isolation amplifier should I use?

Choose the AD210ATI when you need three-port isolation, up to 2500V rms common-mode voltage, gains up to 100V/V, and isolated power available at both the input and the output, all from a single +15V supply. Choose the AD215ATI when low harmonic distortion (−80dB at 1kHz), a buffered output with offset trim and a SIP package matter more; its bandwidth is 300kHz and its isolation rating is 750V rms or 1500V rms.

How long will the AD210ATI remain available?

ATI guarantees production of the AD210ATI for at least 10 years, so designs stranded by the AD210 end-of-life have a long-term source.
