Application notes
• Offset Correction Methods: Laser Trim, e-Trim, and Chopper (Rev. A) | Doc
• Tuning in Amplifiers
Have you ever had the experience of designing an analog gain block with an amplifier that is specified to be unity gain stable only to find that it is oscillating out of control in your circuit? Or have you ever replaced a stable voltage feedback amplifier | Doc
• Single-Supply Operation of Operational Amplifiers
Operation of op amps from single supply voltages is useful when negative supply voltages are not available. Furthermore, certain applications using high voltage and high current op amps can derive important benefits from single supply operation. | Doc

OPAx187 Offers Precision Low-Side Current Measurement Capability

The OPAx187 series operational amplifiers use autozeroing techniques to simultaneously provide lowoffset voltage (1 V), and near zero drift over time and temperature. These miniature, high-precision, low-quiescent current amplifiers offer high-input impedance and rail-to-rail output swing within mV of the rails into high-impedance loads. The input common-mode range includes the negative rail. Either single or dual supplies can be used in the range to 18 V).
