LOW-VOLTAGE RAIL-TO-RAIL OUTPUT CMOS OPERATIONAL AMPLIFIERS WITH SHUTDOWN

DESCRIPTION

The UTC ULV341 devices are single CMOS operational

amplifiers, respectively, with low-voltage, low-power, and rail-to-rail

output swing capabilities. The PMOS input stage offers offset

voltage of 0.3 mV (typical).

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 Vee-0.2V to VCC-0.5V

from the positive supply rail.

The UTC ULV341 (single) in the SOT-26 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).

The UTC ULV341 is suitable for the most space-constrained

applications.

An extended industrial temperature range from -40°C to 125°C

makes the UTC ULV341 suitable in a wide variety of commercial

and industrial applications.
