Device identity and key parametrics
The LMH6502MA is a Texas Instruments variable gain amplifier from the LMH® series, packaged in a 14-SOIC (0.154", 3.90 mm width) for surface-mount assembly. It delivers a -3 dB bandwidth of 130 MHz and a slew rate of 1800 V/µs, making it suited for high-speed gain-control applications such as automatic gain control (AGC) loops, video distribution, and IF/RF signal processing where the gain must be adjusted dynamically without sacrificing bandwidth. The amplifier operates from a single supply span of 5 V to 12 V, drawing 27 mA quiescent supply current. Input bias current is 9 µA, and input offset voltage is 80 mV — figures that should be reviewed against the system error budget, particularly in DC-coupled paths where offset accumulates. Output current capability is 90 mA per channel, sufficient to drive loads in video or RF line-driving stages. The single-circuit configuration (Number of Circuits: 1) means each package handles one gain-control channel; multi-channel designs require one device per channel.
Temperature grade and operating environment
This covers outdoor telecom cabinets, factory-floor automation, and engine-bay electronics without requiring extended-range or military screening. The 14-SOIC package has a typical junction-to-ambient thermal resistance that should be derated if the device is operated near the 85°C upper limit at maximum output current.
