description

The TLV224x family of single-supply operational

amplifiers offers very low supply current of only

1 µA per channel.

The low supply current is coupled with extremely

low input bias currents enabling them to be used

with mega-Ω resistors making them ideal for

portable, long active life, applications. DC

accuracy is ensured with a low typical offset

voltage as low as 600 µV, CMRR of 100 dB, and

minimum open loop gain of 100 V/mV at 2.7 V.

The maximum recommended supply voltage is as high as 12 V and ensured operation down to 2.5 V, with

electrical characteristics specified at 2.7 V, 5 V and 12 V. The 2.5-V operation makes it compatible with Li-Ion

battery-powered systems and many micropower microcontrollers available today including TI’s MSP430.
