The TLV904x-Q1 family of low-power, rail-to-rail input and output operational amplifiers are specifically designed for low-power, always-on applications. This family of amplifiers uses unique transistors that enable operation from ultra-low supply voltage of 1.2V to a standard supply voltage of 5.5V. These unity-gain stable amplifiers provide 350kHz of GBW with an I_Q of only 10µA. The TLV904x-Q1 also has short-circuit current capability of 40mA at 5.5V. This combination of low voltage, low IQ, and high output current capability makes this device quite unique and an excellent choice for a wide range of general-purpose applications. The input common-mode voltage range includes both rails, and allows the TLV904x-Q1 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 an excellent choice for driving low-speed sampling analog-to-digital converters (ADCs). Further, the class AB output stage is capable of driving resistive loads greater than 2kΩ connected to any point between V+ and ground.

The TLV904x-Q1 can drive up to 100pF with a typical phase margin of 45° and features 350kHz gain bandwidth product, 0.2V/μs slew rate with 6.5μV_p-p integrated noise (0.1 to 10Hz) while consuming only 10μA 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 1pA (typical), an input offset voltage of 0.6mV (typical) and a good PSRR, CMRR, and A_OL.
