TLV341

具有关断状态的低压轨至轨输出 CMOS 运算放大器

The TLV34xx devices are single and dual CMOS operational amplifiers, respectively, with low-voltage, low-power, and rail-to-rail output swing capabilities. The PMOS input stage offers an ultra-low input bias current of 1 pA typical and an offset voltage of

0.3 mV typical. For applications requiring excellent dc precision, the A grade TLV34xA has a low offset voltage of 1.25 mV maximum at 25°C.

These single-supply amplifiers are designed specifically for ultra-low-voltage 1.5 V to 5 V operation, with a common-mode input voltage range that typically extends from –0.2 V to 0.5 V from the positive supply rail.

The single and TLV342 dual in the RUG package also offer a shutdown SHDN pin that can be used to disable the device. In shutdown mode, the supply current is reduced to 45 pA typical. Offered in both the SOT-23 and smaller SC70 packages, the TLV341 is suitable for the most space-constrained applications. The dual TLV342 is offered in the standard SOIC, VSSOP, and X2QFN packages.

An extended industrial temperature range from –40°C to 125°C makes the TLV34xx suitable in a wide variety of commercial and industrial applications.
