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.

VCC – Supply Voltage – 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.
