Description
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 TLV341 (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.
