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 lowload impedancesto
be driven. An internal low impedance PHANTOM
GROUND eliminates the need for an external ref­erence voltage or biasingarrangement.

The TS925exhibitsavery lownoise,lowdistortion
and high output current making this device an
excellent choice for high quality, low voltage or
battery operatedaudio/telecomsystems.

The device is stable for capacitive loads up to
500pF.

When the STANDBY mode is enabled, the total
consumption drops to 6µA(V

APPLICATION NOTE

PREAMPLIFIER AND SPEAKER DRIVER USING TS925

by F. MARICOURT

The TS925 is an input/output rail to rail quad
BiCMOSoperationalamplifier. It is able to operate
with low supply voltages (2.7V) and to drive low

output loads suchas 32Ω.
As an illustration of these features, the following

technical note highlights many of the advantages
of thedevicein a global audio application.

APPLICATION CIRCUIT

Figure 1 shows two operators (A1, A4) used in a
preamplifierconfiguration,and the two othersin a
push-pull configuration driving a headset. The
phantom ground is used as a common reference
level (V

The powersupplyis delivered fromtwo LR6batter­ies (2x1.5Vnominal).

Figure1 : ElectricalSchematic

CC/2

).

Preamplifier: the operators A1 and A4 arewired
with a non invertinggain ofrespectively:

• A1# (R4/(R3+R17))

• A4# R6/R5

With the following values chosen :

• R4=22kΩ - R3=50Ω - R17=1.2kΩ

• R6=47kΩ - R5=1.2kΩ,

the gainof the preamplifierchain is thus58dB.

Alternatively, the gain of A1 can be adjusted by
choosinga JFET transistor Q1 instead of R17.
This JFET voltage controlledresistorarrangement

formsan automaticlevelcontrol(ALC) circuit,use­ful in many MIC preamplifier applications. The
meanrectifiedpeak leveloftheoutputsignal enve­lope is used to controlthepreamplifiergain.
