OP291GSZ-REEL7 details

The OP291GSZ-REEL7 is a low-power, high-precision operational amplifier manufactured by Texas Instruments, designed specifically for battery-powered devices and portable instruments. Below is a detailed description of its core features and application scenarios:

Core Parameters

Amplifier Characteristics

1. Number of Channels: Single-channel

2. Input Offset Voltage: 50μV (maximum, Grade B)

3. Input Bias Current: 5pA (maximum, -40°C to +85°C)

4. Open-Loop Gain: 130dB (minimum, RL=10kΩ)

Power Supply and Power Consumption

1. Supply Voltage Range: 2.7V to 36V (single supply) or ±1.35V to ±18V (dual supplies)

2. Quiescent Current: 110μA per amplifier (typical)

3. Unity-Gain Bandwidth: 1.1MHz

4. Slew Rate: 0.5V/μs

Operating Temperature Range

1. Industrial Grade: -40°C to +85°C

Package Type

1. SOT-23-5 (denoted by the GSZ suffix), tape-and-reel packaging (REEL7 indicates a 7-inch reel)

Key Feature Highlights

Ultra-Low Power Consumption

1. With a quiescent current of 110μA, it is ideal for battery-powered devices, extending equipment runtime.

High-Precision Performance

1. Low offset voltage (50μV) and high common-mode rejection ratio (CMRR): 110dB, ensuring accuracy in signal processing.

Wide Supply Range

1. Supports both single and dual power supplies, adapting to various application scenarios.

Strong Driving Capability

1. Rail-to-rail output (within ±100mV of supply rails), capable of directly driving ADCs or other loads.

Typical Application Scenarios

Portable Medical Devices

1. Blood glucose meters, pulse oximeters, electrocardiogram (ECG) monitors.

Industrial Process Control

1. Sensor signal conditioning (e.g., temperature, pressure sensors).

Battery Management Systems

1. Current sensing, battery level monitoring.

Precision Instruments

1. Low-power data acquisition systems, handheld testing equipment.
