Audio Special Purpose seeks to facilitate sound production, and the INA1650IPWR is no exception. Featuring wide supply range, low-noise and low quiescent current operation, the INA1650IPWR is especially useful for active filter applications. Its low bias current allows high gain within a small area and makes the low-noise device suitable for low-voltage audio circuits and the applications of recording, mixing, and DIY.

The INA1650IPWR consists of an ultra-low noise differential INA (instrumentation amplifier) and a power buffer amplifier, giving it the capability to adjust the input impedance, potentiometrically adjust gain, and maximize current drive capability. The INA1650IPWR can be powered from a single voltage source due to the integrated circuit (IC)s\' ability to convert a single supply voltage to a split supply.

The INA1650IPWR\'s input impedance is set internally by two resistors and is created between the two power supply pins. This delivers a low input bias current, allowing a differentially distributed pair of wires, providing good thermal isolation, to be used as a single-ended input. The gain of the amplifier can be adjusted by changing the ratio of the two resistors placed in parallel or by using an external voltage with a resistor divider circuit which sets the denominator in the gain equation.

Additionally, an adjustable high-frequency pole is also included which is used to attenuate high-frequency noise. This pole is adjusted to the desired value by simply changing the external capacitor. All of the control settings are designed to retain their values into a wide operating temperature range.

The INA1650IPWR is designed to ensure excellent low-frequency response. It features low-noise characteristics which makes it suitable for audio applications, with two independent rails eliminating the necessity of a bias supply connection. Its wide supply range and low power consumption also make it a versatile device.

The INA1650IPWR is ideal for applications such as professional audio mixing consoles, powered speakers and subwoofers, DJ levelers, and guitar equipment. It can also be used in microphone preamplifiers, equalizers, noise reduction processors, and line amplifiers. Its versatile design and wide supply range make it suitable for many applications.

Overall, the INA1650IPWR provides an excellent sound quality for its application field. Its power buffer amplifier works together with its differential INA to achieve low noise, low quiescent current operation, allowing it to produce professional quality sound. Its adjustable high-frequency pole reduces the amount of high-frequency noise and its wide supply range makes it suitable for many applications.
