90 kHz GBW, 4 µA per channel — sensor-conditioning sweet spot
The TLV2379IDR is a dual general-purpose op-amp from Texas Instruments with a 90 kHz gain-bandwidth product and a 0.03 V/µs slew rate. Input bias current is 5 pA typical, which keeps DC errors negligible for source impedances up to tens of megohms. The 800 µV input offset voltage is adequate for 12-bit resolution with gain; for higher precision, the faster TLV9362IDDFR (10.6 MHz, 400 µV offset) is a sibling worth evaluating if the power budget allows 2.6 mA per channel instead of 4 µA.
8-SOIC package and board integration
The 5 mA output drive per channel is enough to drive a typical ADC input or a reference buffer; for heavier loads like a 50-ohm cable, an external buffer stage is needed.
