NJU77554V-TE1

Overview

The NJU77554V-TE1 is a quad operational amplifier manufactured by Nisshinbo Micro Devices. It features a gain-bandwidth product of 1.7 MHz and a slew rate of 0.8 V/µs. The device operates on a supply voltage range of 1.8 V to 5.5 V with a quiescent current of 50 µA per channel. It offers an input bias current of 1 pA, an input offset voltage of 1 mV, and a maximum output current of 60 mA. The component supports rail-to-rail output swing and functions within a temperature range of -55°C to +125°C.

Feature Summary

• Quad-channel architecture providing four independent operational amplifiers in a single package
• Rail-to-rail output capability for maximum dynamic signal range utilization
• Ultra-low input bias current of 1 pA suitable for high-impedance sensor interfaces
• Extended industrial temperature operation from -55°C to +125°C

Applications

• Precision signal conditioning for high-impedance transducers
• Battery-powered portable instrumentation requiring low quiescent current
• Industrial data acquisition systems operating in extreme temperatures
• Active filtering circuits in communication equipment

Procurement Notes

Verify the specific suffix TE1 corresponds to the reel packaging configuration required for your assembly line. Confirm that the 14-SSOP footprint matches your PCB design constraints. Ensure the manufacturer is identified as Nisshinbo Micro Devices Inc., resulting from the merger of New Japan Radio and RICOH Micro Devices. Cross-reference the RoHS3 compliance status with your environmental regulations before finalizing procurement orders.

Selection Notes

Select this component when a quad amplifier configuration is necessary to save board space compared to single-channel alternatives. The 1.7 MHz bandwidth is sufficient for general-purpose applications but may require higher-speed devices for wideband signals. Consider the 50 µA quiescent current per channel against total system power budgets. The 14-SSOP package requires appropriate thermal management if multiple channels are driven near their 60 mA limits.

Part Context

This part belongs to the NJU7755x series of operational amplifiers designed for low-voltage analog processing. The series includes variants such as NJU7750, NJU7751, NJU7752, and NJU7754, sharing similar electrical characteristics but differing in channel counts or specific performance optimizations. The NJU77554V-TE1 specifically provides the quad-channel option within this family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by comparing pinouts, electrical parameters, and package dimensions against potential alternative quad operational amplifiers.
