1 µA per channel — the design trade-off that defines this part
The LT1496CS#PBF is a quad general-purpose operational amplifier from Analog Devices (LT® series) built around a single design priority: minimising supply current. Each of its four amplifiers draws 1 µA from the rail, making the complete device a 4 µA quiescent load. That 2.7 kHz gain-bandwidth product tells you the bandwidth budget — this is a DC and near-DC signal chain part, not an audio or control-loop amplifier. The trade-off is deliberate: if your sensor bridge, thermocouple, or battery-monitor circuit needs to run for years on a coin cell, this is the class of op-amp you spec. The 14-SOIC package (3.90 mm width) fits standard four-channel op-amp footprints.
Supply range and output swing — where the flexibility is
The supply span covers 2.2 V minimum to 36 V maximum, which means the same part works in a 2.2 V battery system and a 36 V industrial rail without a secondary regulator. Rail-to-rail output swing preserves signal headroom at low supply voltages — at 2.2 V the output can swing close to both rails, which matters when the ADC reference is the same rail.
Temperature grade — commercial only, plan accordingly
This is a commercial-grade part. If your BOM calls for industrial temperature, look at the LT1496I or similar industrial-temp variants in the same family.
