OPA2673 Datasheet High Output Current Operational Amplifier

Manufacturer: Texas Instruments

Overview: OPA2673 SBOS382H – MAY 2008 – REVISED JUNE 2023 OPA2673 Dual, High Output Current Operational Amplifier With Active Offline Control.

General Description

The OPA2673 provides the high output current and low distortion required for power-line modem driver and test and measurement applications.

The OPA2673 operates on power-supplies ranging from 5.75 V to 13 V and consumes a low 16.5 mA/channel quiescent current to deliver a very high 700 mA output current.

The OPA2673 supports the most demanding power-line modem requirements with an 460 mA specified minimum output current drive (at 25°C).

Key Features

  • Wideband operation: 340 MHz (G = 4 V/V).
  • Unity-gain stable: 600 MHz (G = 1 V/V).
  • High output current: 700 mA.
  • Active offline mode for TDMA.
  • Adjustable power modes:.
  • Full-bias mode: 16.5 mA/channel.
  • 75% bias mode: 12.5 mA/channel.
  • 50% bias mode: 8.5 mA/channel.
  • Off-Line mode: 2.4 mA/channel.
  • Bipolar-supply range: ±3.5 V to ±6.5 V.
  • Single-supply range: 5.75 V to 13 V.
  • High slew rate: 3500 V.
