Description
The TSV358 and TSV324 (dual & quad) are low
voltage versions of LM358 and LM324 commodity
operational amplifiers. TSV321 is the single
version. The TSV321/358/324 are able to operate
with voltage as low as 2.5V and features both I/O
rail-to-rail.
The common mode input voltage extends 200mV
at 25°C beyond the supply voltages while the
output voltage swing is within 100mV of each rail
with 600 Ohm load resistor. These devices offer
1.3MHz of gain-bandwidth product and provide
high output drive capability typically at 65mA-
load.
These performances make the TSV3xx family
ideal for active filters, general purpose low-voltage
applications, general purpose portable devices.
