Active quad CMOS op-amp — parametric fit for battery-powered signal chains
The BU7264F-E2: The BU7264F- is a quad CMOS operational amplifier in a 14-SOP body, combining rail-to-rail output swing with a 2 MHz gain-bandwidth product and 1.1 V/µs slew rate. The CMOS input stage delivers 1 pA typical input bias current and 1 mV input offset — adequate for conditioning high-impedance sensors (photodiodes, piezo films) where FET-input amplifiers are the norm.
Bandwidth and output drive — what the numbers mean for a BOM decision
At 2 MHz GBW, the amplifier's closed-loop bandwidth at a gain of 10 is roughly 200 kHz — sufficient for audio-frequency anti-aliasing or sensor filtering before a low-speed ADC. The 1.1 V/µs slew rate limits full-scale step response: a 2 V output step settles in about 1.8 µs, which sets the minimum sampling interval if the op-amp drives the ADC input directly. Each channel can source or sink 12 mA — enough to drive a reference input or a 2 kΩ load to within 100 mV of the rails, but not intended for heavy cable or headphone loads. Total supply current for all four amplifiers is 1.1 mA typical, keeping the quiescent draw low in multi-channel battery-powered data-acquisition boards.
Housed in a 14-SOIC (4.40 mm body width, 0.173" pitch) with a 14-SOP supplier package designation — a standard footprint that reflows on a conventional lead-free profile without special stencil requirements. ROHS3 compliant per the manufacturer's lifecycle record — no exemption conflicts for EU or UKCA markets.
