Notes:

(*) 52dB using selected L3000N

(1) The datasheet certifies the electrical characteristics at 25

°C. For applications requiring operations in the standard temperature range (0°C

to 70

°C) use L3000N/L3092. If operations are required in the extended temperature range (-40°C to +85°C), use the kit L3000NT/L3092T.

(2) value optimized for programmable COMBO Hybrid Balance Filter
