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. 0.8 0.6 0.4 0.2 0 0 2 4 6 8 10 12 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. DEVICE TLV2241 TLV2242 ...
