Both devices exhibit rail-to-rail output performance for increased dynamic range in single- or split-supply applications. The TLC226x family offers a promise between the micropower TLC225x and the ac performance of the TLC227x. It has low supply current for battery-powered applications, while still having adequate ac performance for applications that demand it. The noise performance has been dramatically improved over previous generations of CMOS amplifiers. Figure 1 depicts the low level of noise voltage for this CMOS amplifier, which has only 200 µA (typ) of supply current per amplifier. EQUIVALENT INPUT NOISE VOLTAGE vs FREQUENCY 60 VDD = 5 V RS = 20 Ω 50 TA = 25°C The TLC226x, exhibiting high input impedance and low noise, are excellent for small-signal 0 10 102 103 104 conditioning for high-impedance sources, such as f - Frequency - Hz piezoelectric transducers. Because of the micropower dissipation levels, these devices work well Figure 1 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...
