What is your ideal op amp for driving audio into 600ohm transformer? We need 0dBm. Input to op-amp is directly from a 3V3 processor DAC (0.2V ->2.9Vout). Single supply rail (can be either 3v3 or 12V).
You can consider our NCS2632. It should meet the requirements you requested.
Supply Voltage from 2.2 V to 5.5 V
Output Voltage into 600 Load
♦ 2 VRMS with 3.3 V Supply Voltage
♦ 3 VRMS with 5 V Supply Voltage
Adjustable Gain from ± 1 V/V to ± 10 V/V
