Zero-drift dual op-amp, 750 kHz GBW, 10 µV offset
The TLV2186IDSGR is a dual-channel zero-drift operational amplifier from Texas Instruments' Zero-Drift series, offering a gain-bandwidth product of 750 kHz and a typical input offset voltage of 10 µV. It draws just 90 µA of supply current per amplifier while delivering rail-to-rail output swing, making it suited for precision signal conditioning in battery-powered or power-sensitive designs.
Supply range 4.5-24 V, industrial temp grade
Operating from a single supply spanning 4.5 V to 24 V, the TLV2186IDSGR covers both 5 V and 12-24 V industrial rails without needing a separate regulator. Rated for -40°C to 125°C ambient (TA), it fits into engine-bay, factory-floor, or outdoor sensor nodes where temperature swings exceed commercial-grade limits. The 8-WSON package with exposed pad (2×2 mm footprint) aids thermal conduction to the PCB ground plane, keeping junction temperature within bounds at the 20 mA per-channel output capability.
Input bias 100 pA, slew rate 0.35 V/µs
With 100 pA typical input bias current, the TLV2186IDSGR loads high-impedance sources like pH probes or thermopiles minimally — the error across a 10 kΩ source is 1 µV, negligible against the 10 µV offset. The 0.35 V/µs slew rate limits the full-power bandwidth to roughly 22 kHz at 2.5 V output swing — adequate for slow-moving sensor signals but not for audio or fast ADC drive stages.
