OP262HRUZ: High-Performance Dual-Channel Rail-to-Rail Operational Amplifier by Analog Devices

The OP262HRUZ from Analog Devices Inc. represents the pinnacle of general-purpose operational amplifier design, combining exceptional performance with versatile functionality. This dual-channel op-amp delivers outstanding specifications that make it ideal for a wide range of precision analog applications across multiple industries.

In-Depth Technical Specifications

1. Dual-Channel Architecture

The OP262HRUZ integrates two complete operational amplifiers in a compact 8-TSSOP package (4.40mm width). This space-saving design reduces PCB footprint by up to 50% compared to using two single op-amps, while maintaining complete electrical isolation between channels. Each channel operates independently with:

• 550 A typical supply current per channel
• 30 mA output current capability
• 1 mV maximum input offset voltage

2. Rail-to-Rail Output Performance

The OP262HRUZ's rail-to-rail output stage ensures maximum dynamic range in low-voltage applications. Testing shows the output swings within 50mV of either supply rail when driving 10k loads, and within 150mV when driving 600 loads. This performance is maintained across the entire 2.7V to 12V supply range.

3. High-Speed Operation

With a 15MHz gain bandwidth product and 13V/ s slew rate, the OP262HRUZ handles demanding signal processing tasks:

• Full power bandwidth: 2.07MHz (for 10Vpp output)
• 0.1% settling time: 1.2 s (to 10V step)
• Phase margin: 60 (typical)

4. Precision Characteristics

The OP262HRUZ delivers precision performance with:

• Input bias current: 260nA (maximum at 25 C)
• Input offset current: 40nA (maximum)
• CMRR: 90dB (typical)
• PSRR: 90dB (typical)

Advanced Applications

1. Professional Audio Equipment

The OP262HRUZ's combination of low noise (8nV/ Hz at 10kHz) and high slew rate makes it ideal for:

• Microphone preamplifiers
• Active crossover networks
• Equalization circuits
• Headphone amplifiers

2. Industrial Measurement Systems

In industrial environments, the OP262HRUZ excels in:

• Strain gauge signal conditioning
• RTD temperature measurement
• 4-20mA current loop receivers
• PLC analog input modules

3. Medical Instrumentation

The amplifier's low power consumption and precision enable:

• ECG front-end circuits
• Blood glucose monitoring
• Portable medical devices
• Patient monitoring systems

Design Considerations

1. Power Supply Configuration

The OP262HRUZ operates from single supplies (3V to 12V) or dual supplies ( 1.35V to 6V). For best performance:

• Use 0.1 F ceramic bypass capacitors at each supply pin
• Maintain supply voltages within 2.7V to 12V total range
• Ensure proper heat dissipation in high-temperature environments

2. PCB Layout Guidelines

To maximize performance:

• Keep input traces short and away from output traces
• Use ground planes for improved noise immunity
• Minimize parasitic capacitance at high-impedance nodes
• Consider guard rings for very high impedance applications
