540 kHz GBW, 0.3 pA bias — precision for slow sensor front-ends
The AD8667ARZ-REEL7 is a dual general-purpose operational amplifier from Analog Devices' DigiTrim® series, built for single-supply signal chains where input bias current and offset voltage dominate the error budget. Gain bandwidth product is 540 kHz, and the slew rate is 0.3 V/µs — this combination sets the usable signal bandwidth below roughly 50 kHz for a gain-of-10 stage, which covers thermocouple conditioning, bridge amplifiers, and battery-monitoring loops. Input bias current is 0.3 pA typical, and input offset voltage is 40 µV — both figures let the amplifier interface directly with high-impedance sources like pH probes or photodiode front-ends without a separate buffer stage.
Industrial temperature range and supply flexibility
Operating temperature spans -40°C to +125°C, which qualifies the part for under-hood automotive modules, industrial PLC analog inputs, and outdoor instrumentation that sees thermal cycling. Supply voltage range is 5 V to 16 V — the rail-to-rail output stage swings within millivolts of both rails, so a single 5 V or 12 V rail powers the full signal chain without a negative supply. Each channel draws 230 µA supply current, and the output can source or sink 50 mA — enough to drive an ADC reference input or a small relay coil directly.
Active lifecycle and package availability
Production status is Active per the manufacturer — no end-of-life notice or last-time-buy window applies, so the part is suitable for both new designs and ongoing production. Packaged in 8-SOIC (0.154" width, 3.90 mm body) on Tape & Reel, with the supplier device package also listed as 8-SOIC — the standard SOIC-8 footprint mates with widely available sockets and automated pick-and-place equipment. RoHS3 compliant — the part ships without the six restricted substances plus the four phthalates, meeting EU Directive 2015/863 requirements for global distribution.
