INA1620 High-Fidelity Audio Operational Amplifier With Integrated Thin-Film Resistors

INA1620 High-Fidelity Audio Operational Amplifier With Integrated Thin-Film Resistors - INA1620
 

Description

The INA1620 integrates 4 precision-matched thin-film resistor pairs and EMI filtering on-chip with a low-distortion, high output current, dual audio operational amplifier. The amplifier achieves a very low,
2.8-nV/√Hz noise density with an ultra-low THD+N of –119.2 dB at 1 kHz and drives a 32-Ω load at 150-mW output power. The integrated thin-film resistors are matched to within 0.004% and can be used to create a large number of very high-performance audio circuits.

The INA1620 operates over a very wide supply range of ±2 V to ±18 V on only 2.6 mA of supply current per channel. The INA1620 also has a shutdown mode, allowing the amplifiers to be switched from normal operation to a standby current that is typically less than 5 µA. Shutdown mode is specifically designed to eliminate click-and-pop noise when transitioning into or out of shutdown mode.

The INA1620 has a unique internal layout for lowest crosstalk, and freedom from interactions between channels, even when overdriven or overloaded. This device is specified from –40°C to +125°C.
