Overview

The TLV904x is a family of low-power, rail-to-rail input and output operational amplifiers specifically designed for battery powered applications. This family of amplifiers utilizes unique transistors that enable operation from ultra low supply voltage of 1.2 V to a standard supply voltage of 5.5 V. These unity-gain stable amplifiers provide 350 kHz of GBW with an IQ of only 10 µA. TLV904x also has short circuit current capability of 40 mA at 5.5 V. This combination of low voltage, low IQ, and high output current capability makes this device quite unique and suitable for suitable for a wide range of general-purpose applications. The input common-mode voltage range includes both rails, and allows the TLV904x series to be used in many single-supply or dual supply configurations. Rail-to-rail input and output swing significantly increases dynamic range, especially in low-supply applications, and makes these devices ideal for driving low speed sampling analog-to-digital converters (ADCs). Further, the class AB output stage is capable of driving resitive loads greater than 2-kΩ connected to any point between V+ and ground.

The TLV904x can drive up to 100 pF with a typical phase margin of 45° and features 350-kHz gain bandwidth product, 0.2-V/μs slew rate with 6.5-μVp-p integrated noise (0.1 to 10 Hz) while consuming only 10-μA supply current per channel, thus providing a good AC performance at a very low power consumption. DC applications are also well served with a low input bias current of 1 pA (typical), an input offset voltage of 0.6 mV (typical) and a good PSRR, CMRR, and AOL.
