Op-amp can be employed with high series resistance input sources

03-01-2020 | Texas Instruments | Power

Texas Instruments TLV6003 Operational Amplifiers use 980nA per channel while providing a very low maximum offset. The reverse battery protection guards the device against an overcurrent condition due to incorrect battery installation. The inputs can be taken 5V more than the positive supply rail with no damage to the device, in harsh environments.

The low supply current is linked with a low input bias current, allowing the op-amp to be employed with high series resistance input sources, including PIR motion detectors and carbon monoxide sensors. DC accuracy is managed with a low max offset voltage of 550┬ÁV (25C), a typical CMRR of 120dB, and a minimum open-loop gain of 112dB at 2.7V.

The device offers a maximum operating supply voltage specified from 2.5V to 16V, with electrical characteristics specified at 2.7V, 5V, and 15V. The device op-amp has a 2.5V operation enabling compatibility with Li-Ion battery-powered systems and are an outstanding candidate for input signal gain and buffering into low-power microcontrollers, such as the MSP430.

Typical applications include flow transmitters, pressure transmitters, motion detectors, blood glucose monitors, and gas detector.
