Frequently Asked Questions
What is the bandwidth and gain of the LTC6400CUD-8#PBF differential amplifier?
The LTC6400CUD-8#PBF provides 3 GHz of bandwidth with a fixed differential gain of 8 dB. This combination allows it to drive high-speed ADCs with bandwidths up to 1 GHz while maintaining low noise and distortion across the full signal chain.
How does the CMRR of the LTC6400CUD-8#PBF affect common-mode noise rejection in ADC driver applications?
With a typical CMRR of 55 dB and a minimum of 39 dB, the LTC6400CUD-8#PBF effectively attenuates common-mode interference on differential signal lines by over 300:1 typically. This performance is critical in ADC driver stages where power supply noise can corrupt 12-bit or 16-bit conversion results.
Which package does the LTC6400CUD-8#PBF use and how does this benefit high-frequency thermal management?
The LTC6400CUD-8#PBF uses a 16-pin QFN package (S-PQCC-N16) with an exposed thermal pad on the bottom. The exposed pad provides a direct thermal path to the PCB ground plane, enabling effective heat dissipation at 3 GHz operation where junction temperature management is critical for maintaining low distortion.
