Overview
The LE87100NQCT is a current feedback amplifier manufactured by Microchip Technology, housed in a 16-VQFN (4x4) package with an exposed pad. It features two independent circuits configured for single-ended output operation. The device operates within a supply voltage range of 8 V to 12 V and draws 16 mA per dual-channel configuration. Key electrical specifications include a gain bandwidth product of 100 MHz, a -3 dB bandwidth of 180 MHz, and a slew rate of 1200 V/µs. It supports an output current of 400 mA per channel and functions reliably across a temperature range of -40°C to 85°C.
Feature Summary
- High-speed current feedback architecture supporting wide bandwidth applications
- Dual-channel configuration integrated into a compact surface-mount package
- Capable of driving high-output currents suitable for line driver requirements
Applications
- Telecommunications interface circuits
- Broadband signal processing systems
- High-frequency buffer and line driver implementations
Procurement Notes
Verify the specific ordering suffix against official Microchip documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure the selected variant matches the required thermal and electrical parameters for the target application environment.
Selection Notes
Select this component when a dual-channel solution with high slew rate and wide bandwidth is required in a small form factor. Consider the 16-VQFN package constraints for thermal management and PCB layout. Evaluate the 400 mA output capability against load requirements to ensure adequate drive strength without exceeding operational limits.
Part Context
This part belongs to the LE87100 series of high-performance amplifiers from Microchip Technology. It is designed for demanding analog signal processing tasks where speed and precision are critical. The device complements other components in communication infrastructure by providing robust signal conditioning and buffering capabilities.
Replacement Considerations
Consult official Microchip substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully before replacing existing designs.
