Operating on a single +12V supply, the OPA2677 consumes a low 9mA/ch quiescent current to deliver a very high 500mA output current. Differential driver applications will deliver < –85dBc distortion at the peak upstream power levels of full rate ADSL. +12V 20Ω 1/2 OPA2677 324Ω Specified on ±6V supplies (to support +12V operation), the OPA2677 will also support a single +5V or dual ±5V supply. Video applications will benefit from its very high output current to drive up to 10 parallel video loads (15Ω) with < 0.1%/0.1° dG/dP nonlinearity.
