OPA4187 Op-Amp
Texas Instruments' op-amp is ideal for a wide variety of general purpose applications
Texas Instruments' OPA4187 op-amps use auto-zeroing techniques to simultaneously provide low-offset voltage of 1 µV and near zero-drift over time and temperature. The miniature, high-precision, low-quiescent current amp offers high-input impedance and rail-to-rail output swing within 5 mV of the rails into high-impedance loads. The input common-mode range includes the negative rail. Single or dual supplies can be used in the range of 4.5 V to 36 V (±2.25 V to ±18 V).
The OPA4187 is offered in 14-pin SOIC, 14-pin TSSOP, and 16-pin WQFN packages. The device is specified for operation from -40°C to +125°C.
