NJU7870VB3Z2-TE1

Overview

The NJU7870VB3Z2-TE1 is an automotive-grade differential amplifier designed for resolver excitation, certified to AEC-Q100 Grade 1 standards. It features a dual-channel architecture with differential voltage input and differential current output, achieving a typical transconductance of 13.5 mAp/Vpp at 10 kHz. The device operates within a supply voltage range of 2.4 V to 5.5 V and draws a typical supply current of 4.5 mA. It supports an operating temperature range from -40°C to +125°C and includes thermal shutdown protection. The component is housed in an SSOP16-B3 package.

Feature Summary

• Integrates two independent channels for simultaneous resolver excitation control
• Provides high precision channel-to-channel matching for transconductance and phase difference
• Includes built-in thermal shutdown circuitry to prevent damage during overload conditions
• Features active shutdown functionality to minimize power consumption when inactive

Applications

• Angle Resolver systems
• Automotive position sensing applications
• Resolver-to-digital converter interfaces

Procurement Notes

Verify the specific Z2 suffix confirms Automotive Grade 1 compliance before integration. Ensure the SSOP16-B3 package dimensions align with the target PCB footprint. Confirm that the required quantity matches the standard taping form specification provided by the manufacturer.

Selection Notes

Select this component for designs requiring integrated dual-channel excitation without discrete resistor networks. Evaluate the maximum output current requirements against the load impedance to ensure operation remains within the linear region. Consider the thermal dissipation characteristics if operating near the upper temperature limits.

Part Context

This part belongs to the NJU7870-Z2 series of special function amplifiers manufactured by Nisshinbo Micro Devices Inc. It is specifically engineered to replace complex discrete circuits in angle sensing applications, offering a compact solution that reduces mounting area while maintaining high signal integrity for automotive grade reliability.

Replacement Considerations

Direct substitutes are not explicitly listed in the official documentation. Verify compatibility with existing system architectures if considering alternative transconductance amplifiers.
