8 Parameter Measurement Information

The various test setup configurations for the OPA855 are shown in #X2027, #X3481, and #X869. When configuring the OPA855 in a gain of +39.2 V/V, feedback resistor RF was set to 953 Ω.

GUID-05A96AE8-5350-4F4D-9B99-B2D25778B3DF.html#X6877 shows 5-dB of peaking with the amplifier in an inverting configuration of –7 V/V with the amplifier configured as shown in #X3481. The 50-Ω matched termination of this circuit configuration results in the amplifier being configured in a noise gain of 5.3 V/V, which is lower than the recommended +7 V/V.
