Maintains accuracy in high-temperature environments with high precision, reducing power consumption

Analog Devices announced the release of the new LTC2063 zero-drift operational amplifier, which typically consumes 1.3μA (up to 2μA) at an input voltage of 1.8V.

This micropower amplifier is characterized by unparalleled precision. Thanks to its high-precision input characteristics, large feedback network resistors can be used, allowing for reduced power consumption while maintaining accuracy even in high-temperature environments.

Rail-to-rail input and output characteristics enable the use of a single power supply and support an enhanced dynamic range. The built-in EMI filter provides 114 dB of EMI rejection performance at 1.8 GHz. Due to the unique 1/f low noise characteristics of the zero-drift architecture applied to this product, the LTC2063 is highly suitable for the amplification and conditioning of low-frequency sensor signals in portable and wireless sensor network applications, as well as in high-temperature industrial and automotive systems.

The LTC2063 is supplied in SOT-23 and SC70 packages. The SC70 version includes a shutdown mode that reduces current consumption to 90nA when the amplifier is not in use, making it suitable for sensor applications with ultra-low power duty cycles. For example, a low-duty-cycle high-precision oxygen detection circuit described in the datasheet consumes an average current of 200 nA or less.

Ross Yu, Marketing Manager at Dust Networks®, stated, “The LTC2063 is a precision measurement solution of a completely different dimension that can be deployed anywhere,” and added, “Its ultra-low power and high-precision characteristics are a perfect match for Dust Networks’ SmartMesh® wireless sensor networks. Thanks to this combination, the scope of application for precision measurement technology, which was previously difficult to use in practice, will expand further in the future.”
