The INA1650IPW is a high-performance dual-channel SoundPlus™ low THD+N differential line receiver launched by Texas Instruments.
1. Basic information
Number of channels: It features dual channels, capable of processing two audio signals simultaneously, effectively enhancing the efficiency and flexibility of audio processing.
Package form: It adopts a 14-pin TSSOP small package, which is compact in size and suitable for layout on circuit boards with limited space, making it convenient for application in various audio devices with high space requirements.
Power supply voltage: Supports an extremely wide power supply voltage range from 4.5V to 36V.
Operating temperature range: The operating temperature range is from -40 °C to 125°C.
2. Performance characteristics
High Common-mode Rejection Ratio (CMRR) : It can achieve an extremely high CMRR of 91dB, effectively suppressing common-mode signal interference and ensuring the purity of audio signals. Even in complex electromagnetic environments, it can accurately extract and amplify differential audio signals, reducing noise and interference.
Low THD+N: For a 20dBu signal level, it can maintain an ultra-low THD+N of -119dB at 1kHz, with extremely low total harmonic distortion and noise. It can restore high-fidelity audio signals, making the sound clearer and more natural.
High input impedance: With a differential high input impedance of 1MΩ, it can reduce the load effect on the previous signal source, ensure the integrity of signal transmission, and better receive and process weak audio signals.
Integrated multiple functions: It integrates an electromagnetic interference (EMI) filter, which can effectively filter out external electromagnetic interference and improve the stability of audio signals; It also has a short-circuit protection function, enhancing the reliability and stability of the chip.
