Dual CMOS op-amp for low-power, high-impedance signal chains
The rail-to-rail output stage and 1 pA input bias current make it a natural fit for battery-powered sensor interfaces, portable instrumentation, and low-frequency active filters where power budget and signal integrity matter more than raw speed.
The 550 kHz gain-bandwidth product sets the usable closed-loop bandwidth for gains above unity. At a gain of 10, expect a -3 dB point around 55 kHz — adequate for audio-frequency conditioning, thermocouple amplification, and control-loop compensation. The 0.25 V/µs slew rate limits large-signal response: a 5 V step settles in roughly 20 µs, so this part is not suited for fast ADC drivers or video buffers. Pair it with a higher-slew-rate sibling like the TLV9362IDDFR (25 V/µs) when driving switched-capacitor inputs or high-speed multiplexers.
Supply current and input bias — the battery-life and sensor-impedance numbers
At 100 µA per channel, the TLV2432ID draws 200 µA total for both amplifiers. In a 3.3 V system that's 660 µW quiescent — negligible in a multi-year battery application. The 1 pA typical input bias current lets you use 10 MΩ feedback resistors without offset errors, which is essential for photodiode transimpedance amplifiers and electrochemical sensor front-ends. The 300 µV input offset voltage is typical for a CMOS stage; if your application demands sub-100 µV precision, consider a chopper-stabilized amplifier.
