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 ref-
erence voltage or biasing arrangement.
The TS925 exhibits a 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 6µA (VCC = 3V).
APPLICATIONS
. Headphone amplifier
. Soundcard amplifier, piezoelectric speaker
. MPEG boards, multimedia systems, ...
. Cordless telephones and portable communica-
tion equipment
. Line driver, buffer
. Instrumentation with low noise as key factor
