OP200EZ

The OP200EZ is a dual operational amplifier (op amp) designed for applications requiring multiple precision op amps and where low power consumption is critical. Offered by Analog Devices, the OP200EZ combines high precision performance with the space-saving and cost-effective benefits of a dual op amp configuration.

Key Features:

1. Precision Performance:
   • The OP200EZ features an extremely low input offset voltage of less than 75 µV, with a drift of less than 0.5 µV/°C over the full military temperature range.
   • This ensures high accuracy and stability in analog signal processing applications.
2. Low Power Consumption:
   • Each amplifier in the OP200EZ draws less than 725 µA of supply current.
   • The total current drawn by the dual OP200EZ is less than half that of a single OP07 op amp, offering significant power savings.
3. High Open-Loop Gain:
   • The open-loop gain of the OP200EZ exceeds 5,000,000 into a 10 kΩ load.
   • This high gain allows for precise amplification of weak analog signals.
4. Low Input Bias Current:
   • The input bias current of the OP200EZ is less than 2 nA.
   • This low bias current minimizes the impact of input bias on the amplified signal.
5. High Common-Mode Rejection Ratio (CMRR):
   • The CMRR of the OP200EZ is over 120 dB.
   • This high CMRR ensures that common-mode signals are effectively rejected, reducing noise and interference in the amplified signal.
6. Low Power Supply Rejection Ratio (PSRR):
   • The PSRR of the OP200EZ is below 1.8 µV/V.
   • This low PSRR minimizes the impact of power supply variations on the amplified signal.
7. On-Chip Zener Zap Trimming:
   • On-chip Zener zap trimming is used to achieve the extremely low input offset voltage of the OP200EZ.
   • This eliminates the need for external offset trimming, simplifying circuit design and reducing cost.
8. Package Options:
   • The OP200EZ is available in an industry-standard 8-lead CDIP package.
   • This compact package allows for easy integration into various electronic circuits.

Applications:

• Precision Instrumentation:
  • The OP200EZ is ideal for precision instrumentation applications, such as data acquisition systems, test and measurement equipment, and medical electronics.
• Low-Power Systems:
  • The low power consumption of the OP200EZ makes it suitable for battery-powered and portable electronics.
• General-Purpose Analog Signal Processing:
  • The OP200EZ can be used in a wide range of general-purpose analog signal processing applications, such as filtering, amplification, and signal conditioning.

Summary:

The OP200EZ is a high-precision, low-power dual operational amplifier that offers excellent performance for a wide range of analog signal processing applications. Its low input offset voltage, high open-loop gain, and low power consumption make it an ideal choice for designers seeking a reliable and versatile op amp solution.
