The OPA197IDR with Precision Amplifiers 36-V, Precision Rail-to-Rail manufactured by Texas Instruments is a low- noise, single-supply, low-power CMOS operational amplifier (op amp). It features rail-to-rail input and output capability, low input offset voltage, and low input bias current. The ultra-low-noise CMOS input stage extends the useful frequency response to beyond 1 MHz, while the high slew rate ensures excellent performance in applications requiring fast settling and fast-transient response. It is pin-compatible with other single-supply precision (Rail-to-Rail) operational amplifiers, such as the OPA2227IDR. The OPA197IDR is ideal for instrumentation gain blocks, low-noise signal conditioning, precision sample-and-hold circuits, and other general-purpose high-precision amplifier applications.
