TLC2254 Rail-to-Rail Very Low-Power Operational Amplifiers

TLC2254 Rail-to-Rail Very Low-Power Operational Amplifiers

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 µA of supply current per channel. This micropowe.

Features

LC225x family consumes only 35 µA 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. EQUIVALENT INPUT NOISE VOLTAGE vs FREQUENCY 60 VDD = 5 V RS = 20 Ω 50 TA = 25°C 40 30 20 The TLC225x amplifiers, exhibiting high input 10 impedance and low noise, are excellent for small-signal conditioning for high-im.
