The TLV6003 is a nanopower operational amplifier consuming only 980 nA per channel, while offering very low maximum offset. Reverse battery protection guards the amplifier from an overcurrent condition due to improper battery installation. For harsh environments, the inputs can be taken 5 V greater than the positive supply rail without damage to the device.
The low supply current is coupled with a low input bias current, enabling the device to be used with high series resistance input sources, such as PIR motion detectors and carbon monoxide sensors. DC accuracy is maintained with a low max offset voltage of 550 µV (25°C), a typical CMRR of 120 dB, and a minimum open-loop gain of 112 dB at 2.7 V.
The maximum operating supply voltage is specified from 2.5 V to 16 V, with electrical characteristics specified at 2.7 V, 5 V, and 15 V. The 2.5-V operation makes this device compatible with Li-Ion battery-powered systems, making the TLV6003 a good choice for input signal gain and buffering into low-power microcontrollers, such as TI’s MSP430.
The TLV6003 is available in a small SOT-23 package.
