Quad op amp
boasts precision specifications
Quad high-performance op amp is ideal for signal conditioning and amplification, particularly in sensor applications with extremely high gain
New from iC-Haus, the iC-HQ is a quad high-performance op amp with an offset of less than 1uV at 3.5MHz gain-bandwidth product, making it ideal for signal conditioning and amplification, particularly in sensor applications with extremely high gain. Small input currents, very low 1/f noise and nonexistence of the typical noise spectrum of auto-zero amplifiers make this op amp perfect for use in measuring amplifiers and audio applications.

The iC-MQ ensures that the parameters set initially for the offset, amplitude and phase correction are kept valid
The device has an extremely low offset temperature drift of only 0.01uV/C and excellent matching among all four op amps.
Its open loop gain, power supply rejection ratio, common mode rejection ratio and load rejection are extremely high and add to the offset voltage only in the submicrovolt range.
A built-in test circuit allows the verification of the offset as part of the functional testing and quality assurance.
The iC-HQ is powered from a single 5V supply.
Input common mode range goes down to 0V.
The 1mA outputs operate rail-to-rail.
The low supply current of 375uA pr op amp allows its use in battery operated devices.
