产品概览
The OPA4727AIPWR is a quad-channel, 20 MHz, high-precision CMOS operational amplifier from Texas Instruments, packaged in a 14-pin TSSOP (PW) package. It utilizes TI’s proprietary e-trim technology for outstanding DC precision — 150 µV max offset and 1.5 µV/°C max drift — and features rail-to-rail output with a supply range of 4V to 12V. The device is specified for operation from -40°C to +125°C.
