Description
The TS921 is a rail-to-rail single BiCMOS
operational amplifier optimized and fully specified
for 3V and 5V operation.
Its high output current allows low-load
impedances to be driven.
The TS921 exhibits very low noise, low distortion
and low offset. It has a high output current
capability which makes this device an excellent
choice for high quality, low voltage or battery-
operated audio systems.
The device is stable for capacitive loads up to
500pF.
Applications
■ Headphone amplifier
■ Piezoelectric speaker driver
■ Sound cards, multimedia systems
■ Line driver, actuator driver
