This circuit can be used to replace the function of conventional differential-amplifier topologies to load the Dc gain on a low level signal. Circuit Graph. So, using a 12V single-supply voltage, with the in amp's output centered on 6V, a rail-to-rail amplifier could swing ±5.5V, but a standard product would have only ±4V output swing (11V p-p versus 8V p-p). 58 5% coupon applied at checkout Save 5% with coupon Views. INA132E/BB : Low Power Single-Supply Difference Amplifier. The second category is directly implemented by a single integrated chip. All devices are fully specified from -40 to +125C. The AD623 is an integrated, single- or dual-supply instrumentation amplifier that delivers rail-to-rail output swing using supply voltages from 3 V to 12 V. The AD623 offers superior user flexibility by allowing single gain set resistor programming and by conforming to the … The gain can be adjusted up to 10,000 by the incorporation of only a single resistor. Technically an op amp that normally is powered by dual supply can be used in single supply if input and output signals are small enough and don’t go to rail voltages. The AD621 REF pin (pin 5) is driven from a low impedance 2V source which is generated by the AD705. 0. United States Patent 5075633 .
