The OP747ARZ-REEL7 from Analog Devices is a quad precision low-power operational amplifier featuring rail-to-rail output operation. It is designed for precision signal conditioning in line-powered and portable instrumentation, remote sensors, current sensing and precision-filter applications.
The OP747 operates from a 3V to 30V single supply or ±1.5V to ±15V dual supplies. It is unity-gain stable and designed for no phase reversal. Internal 500Ω input-protection resistors also allow input voltages to extend above the positive supply under appropriate operating conditions without phase reversal.
At a 5V supply, the OP747 provides a typical input offset voltage of approximately 30µV, with a maximum of 300µV over the specified -40°C to +85°C range. Typical input bias current is 5.5nA, while input offset current is approximately 0.1nA typical.
At 5V, common-mode rejection is 110dB typical, while power-supply rejection is 130dB typical. Typical large-signal voltage gain is approximately 500V/mV under the specified load conditions.
Dynamic performance includes a 0.7MHz typical gain-bandwidth product and 0.2V/µs typical slew rate. The amplifier is unity-gain stable, and Analog Devices specifies stable operation with capacitive loads exceeding 500pF.
Typical input voltage-noise density is 15nV/√Hz at 1kHz, with approximately 0.4µV p-p noise from 0.1Hz to 10Hz. Typical current-noise density is 0.13pA/√Hz at 1kHz.
Power consumption is low, with approximately 235µA typical supply current per amplifier at 5V and 290µA maximum at 25°C. This makes the quad amplifier useful where multiple precision channels are required without excessive power consumption.
With ±15V supplies, the OP747 provides approximately ±30mA typical output-current capability, an input range extending from approximately -15V to +14V, and typical CMRR of 120dB.
The exact OP747ARZ-REEL7 is supplied in a 14-lead narrow SOIC package and is specified for -40°C to +85°C operation. Analog Devices lists the REEL7 option as 1000 pieces per reel, and the exact ordering code is currently PRODUCTION.
