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.
