OPA847IDR High-Speed Current Feedback Operational Amplifier
The OPA847IDR is a high-speed current-feedback operational amplifier (op-amp) manufactured by Texas Instruments, designed for applications requiring exceptional bandwidth, slew rate, and signal fidelity. This unity-gain stable amplifier delivers a remarkable 3,200MHz bandwidth and a 1,800V/µs slew rate, making it ideal for high-frequency signal processing, broadband amplification, and data acquisition systems. Operating from a single +5V power supply (with support for ±2.5V dual supply), the OPA847IDR provides a high output current of ±100mA, enabling driving low-impedance loads with minimal distortion.
Engineered for precision and speed, the OPA847IDR features low input voltage noise (1.6nV/√Hz) and low harmonic distortion (–70dBc at 100MHz), ensuring clean signal amplification in RF, IF, and high-speed analog circuits. Its current-feedback architecture eliminates the gain-bandwidth trade-off typical of voltage-feedback op-amps, allowing consistent performance across a wide range of gains. The device is packaged in a small 8-pin SOIC (DDA), making it suitable for compact PCB designs in communication, test equipment, and high-speed data converters.
For enhanced system integration, the OPA847IDR is optimized for low power dissipation (325mW typical) while maintaining high performance, making it suitable for portable and battery-operated high-frequency equipment. Its robust design includes output short-circuit protection and wide operating temperature range (–40°C to +85°C), ensuring reliability in demanding environments. This op-amp is widely used in optical networking, broadband communication, test instrumentation, and high-speed ADC/DAC buffers.
Alternative Models:
● OPA695IDR: Higher bandwidth (1.6GHz) with integrated charge pump for single-supply operation, ideal for driving ADCs.
● THS3202DGN: Dual high-speed current-feedback op-amp with 2,200MHz bandwidth, suitable for multi-channel systems.
● LMH6702MAX: Ultra-low distortion (–80dBc) current-feedback amp with 1.7GHz bandwidth, optimized for RF applications.
● ADA4899-1YCPZ: Voltage-feedback op-amp with 600MHz bandwidth and ultra-low noise (0.9nV/√Hz), for precision signal conditioning.
