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.
