SBOS901C March 2019 – September 2022 OPA1655 , OPA1656
PRODUCTION DATA
The noise and distortion performance of the OPA165x is exceptional in applications with high source impedances, which makes these devices an excellent choice in preamplifier circuits for moving magnet phono cartridges. The high source impedance of the cartridge, and high gain required by the RIAA playback curve at low frequency, requires an amplifier with both low input current noise and low input voltage noise.
