GENERAL DESCRIPTION
TSV321/TSV358/TSV324 are the most cost-effective
amplifiers for low voltage, low power consumption and
low-cost applications. The rail-to-rail output and rail-to-
rail inputs that exceed power supply range make the
TSV321 series easy to use for very low voltage supply
applications.
Low I
B
feature of these amplifiers allows the parts to be
ideal for many sensor applications. 1MHz GBW and
0.8V/μs slew rate under low power supply voltage can
meet almost all sensor requirement.

ESD CAUTION
ESD (Electrostatic Discharge) sensitive device. Charged devices
and circuit boards can discharge without detection. Although this
product features patented or proprietary protection circuitry,
damage may occur on devices subjects to high energy ESD.
Therefore, proper ESD precautions should be taken to avoid
performance degradation or loss of functionality.
