Texas Instruments TLV9002 Operational Amplifier, 2 Channel, 1MHz, SOIC-8

The Texas Instruments TLV9002 is a high-performance, low-voltage operational amplifier from the TLV900x family, designed for cost-effective and space-constrained applications. This dual-channel op amp operates from a wide supply voltage range of 1.8V to 5.5V, making it ideal for battery-powered devices and modern low-voltage systems. Its rail-to-rail input and output swing capabilities maximise the dynamic range in single-supply applications, ensuring signal integrity even at the voltage rails.

Key performance features include a low input offset voltage of ±0.4 mV for precision and a unity-gain bandwidth of 1 MHz, suitable for a variety of signal conditioning tasks. The device boasts an exceptionally low input bias current of just 5 pA, minimising errors in high-impedance circuits. An internal RFI and EMI filter is integrated to enhance robustness in electrically noisy environments, a critical feature for reliable operation in consumer electronics and industrial settings.

The amplifier is particularly noted for its ability to drive capacitive loads up to 500 pF directly, with a resistive open-loop output impedance that simplifies stabilisation with even higher loads. This, combined with a slew rate of 2 V/µs, ensures stable and fast response in demanding conditions. Housed in a compact SOIC-8 surface-mount package, it is perfectly suited for automated assembly and saves valuable board space.

Typical Applications

• Smoke detectors and safety sensors
• Wearable electronics and portable medical devices
• Small appliances and consumer electronics
• Building site monitoring equipment
• General-purpose amplification, filtering, and buffering in low-voltage systems

With its combination of low power consumption, robust performance, and small footprint, the TLV9002 provides a reliable and economical solution for designers seeking to enhance their analog circuit performance.
