TLV2244 四路微功耗 2.5V RRIO 单电源放大器

The TLV224x family of single-supply operational amplifiers offers very low supply current of only 1 uA per channel.

The low supply current is coupled with extremely low input bias currents enabling them to be used with mega- resistors making them ideal for portable, long active life, applications. DC accuracy is ensured with a low typical offset voltage as low as 600 uV, 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
