OP747

Category: Amplifiers, Analog Devices Inc, Electronics

Overview

The OP777, OP727, and OP747 are a family of precision operational amplifiers from Analog Devices, engineered for single-supply operation. They feature a combination of low voltage offset and low input bias current, making them suitable for high-precision applications.

Features

These amplifiers boast a low offset voltage with a maximum of 100 µV and an input bias current with a maximum of 10 nA. They are designed to operate effectively on single supplies ranging from 3.0 V to 30 V, or dual supplies from ±1.5 V to ±15 V. Another highlight is their low supply current requirement, with no more than 300 µA per amplifier. Stable at unity gain, these amplifiers can handle capacitive loads exceeding 500 pF without phase reversal. Inputs are safeguarded with 500 Ω series resistors, allowing input levels several volts above the positive supply. The amplifiers are appropriate for a variety of applications, with specific mentions of current sensing, battery-powered instrumentation, remote sensors, and precision filters.

Applications

Their characteristics make them ideal for line or battery-powered instrumentation, current sensing applications such as shunt monitoring, signal conditioning in remote sensors, and crafting precision filters. The amplifiers are compatible with other standards, with the OP727 specifically mentioned as being pin-compatible with the LT1013.

Variants

The OP777 is a single amplifier available in 8-lead MSOP and 8-lead SOIC packages; the OP727 is a dual amplifier available in 8-lead TSSOP and 8-lead SOIC packages with a note on differing pin configuration from standard operational amplifiers; and the OP747 is a quad amplifier available in 14-lead TSSOP and SO packages. All variants are designed for the extended industrial temperature range (-40°C to +85°C).

Package and Compatibility

These precision amplifiers come in several compact packaging options, like the 8-Lead MSOP, 14-Lead SOIC, 8-Lead TSSOP, and others. These options cater to diverse integration requirements and space constraints. The available package types are further confirmed to be available in tape and reel form, primarily catered to surface-mount assembly processes.
