Product Details

describe:

The INA1620 integrates four precisely matched thin-film resistor pairs and on-chip EMI filtering with a low distortion, high output current, ADS8328IRSAT dual audio operational amplifier. The amplifier achieves a very low 2.8nV/√Hz noise density, an ultra-low THD+N of –119.2dB at 1kHz, and drives a 32Ω load with 150mW 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, drawing only 2.6 mA of supply current per channel. The INA1620 also features a shutdown mode that allows the amplifier to switch from normal operation to a standby current of typically less than 5 μA. Shutdown mode is specifically designed to eliminate clicks when entering or exiting shutdown mode.

The INA1620 has a unique internal layout that minimizes crosstalk and produces no channel-to-channel interaction even when overloaded or overloaded. The device is specified over a temperature range of –40°C to +125°C.
