The OPAx210 are the next generation of the OPAx209 operational amplifiers. The OPAx210 offer improved input offset voltage, offset voltage temperature drift, input bias current, and lower 1/f noise corner frequency. In addition, these devices offer excellent overall performance with high CMRR, PSRR, and A_OL.The OPAx210 precision operational amplifiers are unity-gain stable, and free from unexpected output and phase reversal. Applications with noisy or high-impedance power supplies require decoupling capacitors placed close to the device pins. In most cases, 0.1-µF capacitors are adequate. Section 7.2 shows a simplified schematic of the OPAx210. The die uses a SiGe bipolar process and contains 180 transistors.
