Dual general-purpose op-amp for extended-temp signal chains
The STMicroelectronics TS1872AIST is a dual-channel general-purpose op-amp with a 1.8 MHz gain-bandwidth product and rail-to-rail output stage. The 80 mA per-channel output drive can directly feed an ADC input or drive a small load without a separate buffer.
The 1.8 MHz gain-bandwidth product sets the usable closed-loop gain range: at a gain of 10 you have about 180 kHz of small-signal bandwidth, enough for audio, low-frequency vibration monitoring, or slow ADC front-ends. The 0.6 V/µs slew rate limits full-power response to roughly 95 kHz at 2 V output swing — adequate for most sensor and control loops, but not for high-speed video or fast-switching filters. Input offset voltage is rated at 1 mV typical, input bias current at 70 nA, both within the range you expect for a general-purpose bipolar-input amplifier.
