3 Description

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 batterypowered

systems, making the TLV6003 a good

choice for input signal gain and buffering into lowpower

microcontrollers, such as TI’s MSP430.

The TLV6003 is available in a small SOT-23

package.
