Texas Instruments (TI, Dallas, TX) announced the OPA2677 high output current operational amplifier. Operating on a single 12V supply, the OPA2677 consumes 9mA/chan quiescent current to deliver a 500mA peak output current. The guaranteed minimum output current is greater than 380mA with low harmonic distortion.
The OPA2677 is packaged in an SO-14. Two logic-control lines allow four quiescent power settings. These include full power, power cutback for short loops, idle state for no signal transmission but line-match maintenance, and shutdown for power-off with a high-impedance output. Specified on +/-6V supplies, the OPA2677 will also support a single 5V or dual +/-5V supply.
Pricing for the OPA2677 ranges between $2.30 to $2.61 per unit in quantities of 1,000 or greater.
