3 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.
