Overview
The LMH6502MAX/NOPB is a wideband, low power linear-in-dB variable gain amplifier manufactured by Texas Instruments. It features a bandwidth of 130 MHz at closed-loop gain and supports a maximum gain of 40 dB. The device operates within a supply voltage range of 5 V to 12 V and functions across an operating temperature range of -40°C to 85°C. It utilizes a 14-pin SOIC package group and exhibits a typical slew rate of 1800 V/µs.
Feature Summary
- Provides linear-in-dB variable gain control for precise signal amplitude adjustment
- Designed for wideband applications with high-speed signal processing capabilities
- Optimized for low power consumption in portable and battery-operated systems
Applications
- Wireless communication infrastructure equipment
- Test and measurement instrumentation requiring adjustable gain stages
- Video signal processing circuits demanding wide bandwidth
Procurement Notes
Verify the complete part number including the suffix /NOPB to ensure lead-free compliance and specific packaging configuration. Confirm that the 14-pin SOIC package variant matches the target PCB footprint requirements. Cross-reference the manufacturer datasheet for the latest electrical specifications and thermal characteristics before finalizing procurement decisions.
Selection Notes
Select this component when a single-channel variable gain amplifier with wide bandwidth is required. Ensure the design accommodates the specified 5 V to 12 V supply voltage range. Consider the 14-pin SOIC package constraints during layout planning. Verify that the 130 MHz bandwidth meets the system's frequency response needs.
Part Context
This device belongs to the LMH6502 family of wideband amplifiers from Texas Instruments. It is functionally related to variants such as LMH6502MA/NOPB and LMH6502MT/NOPB, which share similar core specifications but may differ in package type or manufacturing lot details. All variants maintain the linear-in-dB gain characteristic essential for RF and IF signal chains.
Replacement Considerations
Direct substitutes include LMH6502MA/NOPB and LMH6502MT/NOPB. Verify pinout compatibility and package dimensions before substitution. Ensure that any alternative component meets the same 130 MHz bandwidth and 40 dB gain specifications.
