Description
The
TS925
is
a
rail-to-rail
quad
BiCMOS
operational amplifier optimized and fully specified
for 3V and 5V operation.
High output current allows low load impedances to
be driven. An internal low impedance phantom
ground eliminates the need for an external
reference voltage or biasing arrangement.
The TS925 exhibits very low noise, low distortion
and high output current making this device an
excellent choice for high quality, low voltage or
battery operated audio/telecom systems.
The device is stable for capacitive loads up to
500pF. When the STANDBY mode is enabled, the
total consumption drops to 6
µA (V
CC = 3V).
Applications
Headphone amplifier
Soundcard amplifier, piezoelectric speaker
MPEG boards, multimedia systems...
Cordless telephones and portable
communication equipment
Line driver, buffer
Instrumentation with low noise as key factor
