Descripción

Productos

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.

Introducción del producto:OPA4727AIPWR Presentación del producto

The OPA4727 is a quad-channel version of the OPA727 high-precision CMOS operational amplifier family from Texas Instruments. It uses e-trim, a package-level digital trimming technology, to achieve outstanding DC precision with offset voltage as low as 150 µV maximum and drift of 1.5 µV/°C maximum. The trimming is performed after packaging to eliminate shifts caused by assembly stress, and the devices are trimmed over temperature to correct for offset drift. With 20 MHz GBW, 30 V/µs slew rate, and 0.0003% THD+N, the OPA4727 delivers excellent AC performance alongside its DC precision, making it suitable for a wide range of signal conditioning and audio applications.

Principio de funcionamiento:OPA4727AIPWR Principio de funcionamiento

The OPA4727 uses a CMOS input stage with e-trim correction to achieve ultra-low offset voltage and drift. The e-trim process performs digital trimming of internal resistor networks after the die is encapsulated in its package, compensating for stress-induced offset shifts that occur during molding. The input stage features a folded-cascode architecture with active load for high CMRR and PSRR. The output stage is a rail-to-rail CMOS push-pull amplifier that can swing to within 150 mV of either supply rail with a 100 kΩ load. Each of the four channels operates independently with its own feedback path, sharing only the supply pins. The low 500 pA input bias current is achieved through the CMOS input pair, making the device suitable for high-impedance source applications such as transimpedance amplifiers for optical monitoring.
