AH831 - Faraday Technology

AH831
NEAR 601 FULLY BUFFERED
UV POST FILTER
The AH831 is a tightly specified post D-to-A filter for use in colour difference applications. The filter
has been optimised with an accurate factory-set gain of 6dB. Use of the latest operational amplifiers
results in low current consumption and good differential phase and gain performance.
