OPA2333AQDGKRQ1

这款CMOS运算放大器OPA2333-Q1使用专有自动校准技术，可在随时间推移和温度变化的同时提供超低的失调电压（10μV，最大值）以及几乎为零的温漂。这些高精度、低静态电流微型放大器可提供高阻抗输入（共模范围在电源轨基础上向外扩展了100mV）和轨至轨输出（摆幅在相对于电源轨50mV以内）。此器件可以使用低至1.8V (±0.9V) 和高达5.5V (±2.75V)的单电源或双电源，并且针对低电压、单电源运行情况进行了优化。 OPA2333-Q1提供出色的高共模抑制比(CMRR)，而不存在与传统互补输入级关联的交叉。该设计可在驱动模数转换器(ADC)的过程中实现优异的性能，而不会降低微分线性。 OPA2333-Q1的额定工作温度范围为 -40°C 至 +125°C。 The OPA2333-Q1 device is a zero-drift, low-power, rail-to-rail input and output operational amplifier. The device operates from 1.8 V to 5.5 V, is unity-gain stable, and is designed for a wide range of general-purpose applications. The zero-drift architecture provides ultra-low offset voltage and near-zero offset voltage drift. The OPA2333-Q1 is unity-gain stable and free from unexpected output phase reversal. The device uses a proprietary auto-calibration technique to provide low offset voltage and very low drift over time and temperature. The OPA2333-Q1 input common-mode voltage range extends 0.1 V beyond the supply rails. The device is designed to cover the full range without the troublesome transition region found in some other rail-to-rail amplifiers. Normally, input bias current is approximately 70 pA; however, input voltages exceeding the power supplies can cause excessive current to flow into or out of the input pins. Momentary voltages greater than the power supply can be tolerated if the input current is limited to 10 mA.
