description/ordering information
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 0.9-V/µs
slew rate.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
