TLV342 低电压轨至轨输出 CMOS 运算放大器
The TLV341, TLV342, and TLV344 are single, dual, and quad 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 (typ) and an offset voltage of 0.3 mV (typ). For applications requiring excellent dc precision, the A grade (TLV34xA) has a low offset voltage of 1.25 mV (max) 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. Additional features include 20-nV/
Hz voltage noise at 10 kHz, 2.3-MHz unity-gain bandwidth, and 0
