LM4951A: Gain Error of LM4951A

Part Number: LM4951A

Hello team,

My customer is evaluating the LM4951A with setting Ri=100kΩ(95.0kΩ~105.0kΩ) and Rf=510kΩ(484.5kΩ~535.5kΩ).

Base on the above setting, the gain range is 9.2~11.3(typ: 10.2). But the result they got is 8.9(Vinp-p=0.080V, Voutp-p=7.2V), and this value is not met the range.

Is there any variation in gain of the LM4951A?

If so, can you provide us the data of the variation?

Best regards,

Shotaro
