OPA4197IPWR operational amplifier CMOS 4 Circuit Rail-to-Rail 14-TSSOP
The OPA4197IPWR from Texas Instruments is a quad, high-voltage, precision operational amplifier built on a 36V CMOS process and housed in a 14-TSSOP (PW) package, specified over the –40°C to +125°C industrial temperature range. As part of the OPAx197 family, it combines rail-to-rail input and output swing with a maximum input offset voltage of ±100 µV and a typical offset drift of ±0.5 µV/°C, enabling accurate signal conditioning in high-resolution data acquisition systems and industrial control loops. The device operates from single supplies of +4.5 V to +36 V or dual supplies of ±2.25 V to ±18 V, making it well suited for high-voltage analog front ends and PLC/DCS modules where robust signal integrity is essential.
The OPA4197IPWR incorporates EMI- and RFI-filtered inputs to suppress high-frequency interference, which is particularly valuable in electrically noisy industrial environments. Its typical quiescent current is 1 mA per amplifier, balancing precision performance with moderate power dissipation for multi-channel configurations. Packaged in a 14-pin TSSOP, it is suitable for space-constrained PCB layouts while still allowing easy prototyping and manual inspection. The combination of low offset, low noise, wide supply range, and robust output drive makes this device a strong choice for applications such as 4–20 mA loop receivers, precision current sensing, bridge sensor interfaces, and low-side or high-side signal conditioning in industrial instrumentation and motor-control systems.
