INA149: Seek for alternative materials or alternative solutions

Part Number: INA149
Other Parts Discussed in Thread: VCA821, VCA824

Hi team,

My customer wants to find a alternative device or alternative solutions to take over AD8130ARMZ-REEL7 (Low cost Differential Receiver Amplifiers) 

Could you help me to find a P2P device or our other alternative device?

Best regards,

Andy Liu

  • Hello Andy,

        We do have alternative solutions for high speed differential input amplifiers such as the VCA821 and VCA824, but these are not P2P devices. These are higher bandwidth and slew rate with the same power voltage supply range as the AD8130. If application is not space constrained, it is possible to construct your own differential to single ended amplifier using multiple amplifiers and resistor components like as shown below:


        Or another solution would be to use a FDA or fully differential amplifier and through a resistor, then ground the unused output.

    Thank you,
