Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADA4945-1ACPZ is a low-noise, low-distortion, fully differential amplifier with two selectable power modes. The device operates with a wide supply voltage range of 3 V to 10 V. Low DC offset, DC offset drift and excellent dynamic performance make the ADA4945-1 ideal for a variety of data acquisition and signal processing applications. The device is ideal for driving high-resolution, high-performance successive approximation registers (SAR) and sigma-δ analog-to-digital converters (ADCs) operating with 4 mA static current (full power mode).
