Amplifiers

DVGA900 MHzSPI controlledDifferential outputWQFN-16

LMH6518SQ/NOPB is a 900 MHz SPI-programmable variable gain amplifier for differential high-speed signal paths, with 40 dB gain control in 2 dB steps.

Best for

  • High-bandwidth differential ADC driving
  • Oscilloscope analog front ends
  • Programmable RF/IF or data-acquisition gain stages

Avoid if

  • A single-supply low-voltage amplifier is required
  • A low-frequency or low-power-only signal path is required
  • A single-ended output is required without external conversion

Check before use

  • Confirm the ADC input common-mode range and differential impedance.
  • Use controlled-impedance, symmetric input and output routing.
  • Confirm that the selected bandwidth filter supports the required signal bandwidth.
