description

The TLC2252 and TLC2254 are dual and

quadruple operational amplifiers from Texas

Instruments. Both devices exhibit rail-to-rail

output performance for increased dynamic range

in single- or split-supply applications. The

TLC225x family consumes only 35 

µ

A of supply

current per channel. This micropower operation

makes them good choices for battery-powered

applications. The noise performance has been

dramatically improved over previous generations

of CMOS amplifiers. Looking at Figure 1, the

TLC225x has a noise level of 19 nV/

Hz at 1kHz;

four times lower than competitive micropower

solutions.

The TLC225x amplifiers, exhibiting high input

impedance and low noise, are excellent for

small-signal conditioning for high-impedance

sources, such as piezoelectric transducers.

Because of the micropower dissipation levels,

these devices work well in hand-held monitoring

and remote-sensing applications. In addition, the

rail-to-rail output feature with single or split

supplies makes this family a great choice when interfacing with analog-to-digital converters (ADCs). For

precision applications, the TLC225xA family is available and has a maximum input offset voltage of 850 

µ

V. This

family is fully characterized at 5 V and 

±

5 V.

The TLC2252/4 also makes great upgrades to the TLC27L2/L4 or TS27L2/L4 in standard designs. They offer

increased output dynamic range, lower noise voltage, and lower input offset voltage. This enhanced feature set

allows them to be used in a wider range of applications. For applications that require higher output drive and

wider input voltage ranges, see the TLV2432 and TLV2442 devices. If the design requires single amplifiers,

please see the TLV2211/21/31 family. These devices are single rail-to-rail operational amplifiers in the SOT-23

package. Their small size and low power consumption, make them ideal for high density, battery-powered

equipment.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:

1. All voltage values, except differential voltages, are with respect to the midpoint between VDD+  and VDD – .

2. Differential voltages are at IN+ with respect to IN –. Excessive current flows when input is brought below VDD – – 0.3 V.

3. The output may be shorted to either supply. Temperature and/or supply voltages must be limited to ensure that the maximum

dissipation rating is not exceeded.

APPLICATION INFORMATION

driving large capacitive loads

The TLC225x is designed to drive larger capacitive loads than most CMOS operational amplifiers. Figure 56

and Figure 57 illustrate its ability to drive loads up to 1000 pF while maintaining good gain and phase margins

(R

null

 = 0).

A smaller series resistor (R

null

) at the output of the device (see Figure 60) improves the gain and phase margins

when driving large capacitive loads. Figure 56 and Figure 57 show the effects of adding series resistances of

10 

, 50 

, 100 

, 200 

, and 500 

. The addition of this series resistor has two effects: the first is that it adds

a zero to the transfer function and the second is that it reduces the frequency of the pole associated with the

output load in the transfer function.

The zero introduced to the transfer function is equal to the series resistance times the load capacitance. To

calculate the improvement in phase margin, equation 1 can be used.
