St MicroElectronics Quad Operational Amplifier 4 Channel 1.3MHz SOIC

The St MicroElectronics Quad Operational Amplifier provides four independent high-gain amplifiers with a 1.3 MHz typical gain bandwidth product in a surface-mount SO14 (SOIC) package.

Overview

This low-power quad operational amplifier integrates four independent, high-gain amplifiers with internal frequency compensation, allowing stable operation without external components. It can operate from a single power supply over a broad voltage range or from split supplies, and its low supply current drain remains independent of the supply voltage magnitude.

Key Features

• Four independent channels in a single device
• Internal frequency compensation
• Single-supply operation from +3 V to +30 V
• Dual-supply operation from ±1.5 V to ±15 V
• Input common-mode voltage range that includes ground
• Typical gain bandwidth product of 1.3 MHz
• Typical slew rate of 0.4 V/µs
• Typical input bias current of 20 nA and input offset voltage of 2 mV
• Typical common mode rejection ratio of 80 dB

Physical and Operating Details

The device is housed in an SO14 (SOIC) package with 14 pins and uses surface-mount mounting. Its operating temperature range is 0 °C to 70 °C, suiting standard industrial and consumer environments. Listed dimensions are width 3.3, depth 1.5 and height 4.3, with a product weight of 4.536 g.

Power Consumption

With a typical supply current of 0.7 mA at +5 V, the amplifier offers low power consumption, which supports energy-efficient battery-powered designs. The quad configuration allows multiple stages to be integrated into one device, reducing board space and component count.

Applications

Suited to general-purpose signal conditioning, filter circuits, control systems and analog signal processing tasks, this operational amplifier is a practical choice for engineers requiring a low-power solution for multiple amplifier stages.
