5Ω 301Ω 250Ω 250Ω +5 1/3 OPA3681 10 (V1 – V2) –5 499Ω +5 499Ω 1/3 OPA3681 V2 –5 High Speed INA (>120MHz) DESCRIPTION The OPA3681 sets a new level of performance for broadband triple current-feedback op amps.
Operating on a very low 6mA/ch supply current, the OPA3681 offers a slew rate and output power normally associated with a much higher supply current.
A new output stage architecture delivers a high output curr...
