Description

Using the LMH6629 and OPA684 op amps, this reference design deals with the difficulties and limitations of developing very high gain, multistage amplifier circuits. Supported by a full scale application report including theory, simulations, board design and evaluation, this design can be easily adjusted for a given application.

Features
  • High Voltage Gain - up to 120,000 V/V
  • High Bandwidth - Flat Band 100 kHz - 4 MHz @ 120,000 V/V
  • Low Supply Operation (+/-2.5 V)
  • Low Component Count
  • This reference design has been lab tested and is supported with design files and an application report
