Overview

In recent years, advancements in electrification and mounting density have increased the amount of environmental noise in electric vehicles and cars equipped with ADAS. Generally, however, it is extremely difficult to carry out noise evaluation on individual boards and systems during automotive development since it must be performed after assembly. What’s more, some results require improvements such as large-scale EMI countermeasures to lower noise.

High EMI Immunity Op Amp Development Concept

The EMARMOUR™ series is designed to prevent malfunctions due to noise without the need to take special application measures. The latest BD8758xY series in particular has demonstrated superior performance under four international noise evaluation tests. For example, in ISO 11452-2 radio wave emission testing conducted by vehicle manufacturers, the output voltage of standard products fluctuates by more than ±300mV in all frequency bands, while the new BD8758xY series achieves ±10mV or less. At the same time, the CMOS element structure enables accurate, high-speed signal amplification – without being affected by external noise when installed inside the targeted sensor applications. This significantly improves reliability while reducing design production-hours in a wide range of applications, including anomaly detection systems.

Key Features

1. Breakthrough noise immunity reduces noise design resources considerably

Developed as part of the EMARMOUR™ series of op amps, these newest models achieved unprecedented performance in four international noise evaluation tests (ISO 11452-2 Radio Wave Emission Test, ISO 11452-4 Bulk Current Injection Test, ISO 11452-9 Proximity Antenna Immunity Test, and IEC 62132-4 Direct RF Power Injection Test ) conducted in ROHM’s own anechoic chamber.

BD8758xY Noise Test Evaluation Results

For example, in the ISO 11452-2 radio wave emission test, the output voltage of standard products can fluctuate by ±300mV or more across the entire noise frequency band, while ROHM’s latest products achieve unprecedented noise immunity that limits variation to less than ±10mV. This not only eliminates the need for countermeasures at each frequency (i.e. a total of 10 CR filter components for a 2ch op amp), but also reduces the noise design resources for sensors and other components that play an important role in the system, contributing to reduced application design effort and improved reliability.

2. High accuracy simulation model prevents rework after prototyping

Circuit Current vs Temperature Change

‘ROHM Real Model’ is a new high accuracy SPICE model that utilizes original model-based technology to faithfully reproduce the electrical and temperature characteristics of the actual IC, resulting in a perfect match between the IC and simulation values. This ensures reliable verification, contributing to more efficient application development – for example by preventing rework after prototyping.

This SPICE model is now available on ROHM’s website. https://www.rohm.com/products/amplifiers-and-linear/operational-amplifiers/standard/emi-automotive-input-output-rail-to-rail

Application Examples

  • EV/HEV inverters, engine control units, eCall (vehicle emergency call system), car navigation/air conditioning systems
  • Industrial factory automation equipment, measurement equipment, measuring instruments, servo systems, and sensor systems
  • and other automotive/industrial applications sensitive to noise
