7 Detailed Description

7.1 Overview

The OPA207 precision operational amplifier replaces the industry standard OP-177. The OPA207 offers

improved noise, wider output voltage swing, has twice the bandwidth, ten times the slew rate and consumes only

half the quiescent current as the OP-177. Additional features include ultralow offset voltage and drift, low bias

current, high common-mode rejection, and high power supply rejection.

7.3 Feature Description

The OPA207 is unity-gain stable and free from unexpected output phase reversal, making it easy to use in a

wide range of applications. Applications with noisy or high-impedance power supplies may require decoupling

capacitors close to the device pins. In most cases 0.1-μF capacitors are adequate.

7.3.1 Operating Voltage

The OPA207 operates from ±2.25 V to ±18 V supplies with excellent performance. Key parameters are assured

over the specified temperature range, –40°C to 125°C. Most behavior remains unchanged through the full

operating voltage range (±2.25 V to ±18 V). Parameters which vary significantly with operating voltage or

temperature are shown in Typical Characteristics.
