Dual general-purpose op-amp in 8-SOIC
The OP295GSZ-REEL is an Analog Devices dual general-purpose operational amplifier in an 8-SOIC package, surface-mount with 0.154" (3.90 mm) body width. Rated for -40 °C to 125 °C operating temperature, it fits industrial and automotive-temperature environments where the ambient can swing beyond commercial limits. Supply span runs from 3 V to 36 V — single-supply or split-rail designs both work without a separate regulator tap.
Gain bandwidth and slew rate — what they mean for signal conditioning
75 kHz gain-bandwidth product sets the usable closed-loop bandwidth: at a gain of 10 the -3 dB point is roughly 7.5 kHz, adequate for slow sensor outputs (temperature, pressure, strain) but not audio or fast control loops. 0.03 V/µs slew rate limits the large-signal response — a 10 V output step slews in about 330 µs, so this part is for DC and low-frequency AC signals, not pulse or waveform generation. Rail-to-rail output lets the signal swing to within millivolts of the supply rails, preserving dynamic range when running from a 3 V rail.
Input characteristics and output drive
Input bias current is 7 nA typical — high enough that a 1 MΩ source resistor drops 7 mV across it, so keep source impedance below 100 kΩ for offset-critical paths. 300 µV input offset voltage typical means the DC error at the output is the offset times the noise gain; for a gain of 10 that is 3 mV referred to output. Each output can source or sink 25 mA, enough to drive an ADC input, a comparator, or a small relay coil through a series resistor.
Active production — sourcing and compliance
ROHS3 compliant, so it meets the current EU restriction directive without exemptions. Available in Tape & Reel (TR) or Cut Tape (CT) — the -REEL suffix indicates reel packaging for automated pick-and-place.
