APPLICATION INFORMATION
single-supply operation
While the TLC2810Z performs well using
dual-power supplies (also called balanced or split
supplies), the design is optimized for single-sup-
ply operation. This includes an input common-
mode voltage range that encompassesground as
well as an output voltage range that pulls down to
ground. The supply voltage range extends down
to 4 V, thus allowing operation with supply levels
commonly available for TTL and CMOS.
Many single-supply applications require that a
voltage be applied to one input to establish a
reference level that is above ground. This virtual
ground can be generated using two large
resistors, but a preferred technique is to use a
virtual ground generator such as the TLE2426 (see Figure 31). The TLE2426 supplies an accurate voltage equal
to V
DD
/2, while consuming very little power and is suitable for supply voltages of greater than 4 V.
The TLC2810Z works well in conjunction with digital logic. However, when powering both linear devices and
digital logic from the same power supply, the following precautions are recommended:
1.
Power the linear devices from separate bypassed supply lines (see Figure 32). Otherwise, the linear
device supply rails can fluctuate due to voltage drops caused by high switching currents in the digital logic.
2.
Use proper bypass techniques to reduce the probability of noise-induced errors. Single capacitive
decoupling is often adequate. However, RC decoupling may be necessary in high-frequency applications.
