Product details

Quad CMOS op-amp for multi-channel signal conditioning

Rail-to-rail output and a 7 MHz gain-bandwidth product suit it for multi-channel sensor front-ends, ADC drivers, and active filters where signal swing near the supply rails matters. The 10 V/µs slew rate handles fast pulse edges without excessive distortion, and the 1.1 mA per channel supply current keeps the total power budget tight in battery-operated or multi-pole filter arrays.

Supply span is 3.5 V to 12 V. Each channel sources or sinks 20 mA. Input bias current is 1 pA.

The 14-TSSOP footprint (4.40 mm wide) is a common quad-op-amp layout, making PCB routing straightforward alongside other 14-pin TSSOP devices.
