ULTRA LOW NOISE DUAL OPERATIONAL AMPLIFIER

DESCRIPTION

The UTC UM2122 is an ultra low noise dual operational

amplifier built using an advanced bipolar process. It can be

operated at a very low supply voltage (±2V), while maintaining a

low saturation output voltage.

The features of ultra low noise, low operating voltage, and low

saturation voltage are suitable for microphone amplifier of digital

audio items such as portable MD, DAT, and others.

FEATURES

* Operating Voltage: ±2.0V ~ ±7.0V

* Ultra Low Noise Voltage: 1.5nV/√Hz (typ.) @ f=1kHz.

* Low Saturation Output Voltage: 0.3V (typ.)

* Bipolar Technology
