These miniature, highprecision, low quiescent current amplifiers offer high input impedance and rail-to-rail output swing within 15 mV of the rails, making them ideal for industrial applications.
The input common-mode range includes the negative rail.
Either single or dual supplies can be used in the range of 4 V to 36 V (±2 V to ±18 V).
The quad version is available in 14-pin SOIC and 14pin TSSOP packages.
All versions are specified for operation from –40°C to +125°C.
