by Burr Brown/Texas Instruments _ > 1MHz TRANSIMPEDANCE BANDWIDTH _ EXCELLENT LONG-TERM VOS STABILITY _ DYNAMIC RANGE: 4 to 5 Decades The OPA380 family of transimpedance amplifiers provides high-speed (90MHz Gain Bandwidth [GBW]) operation, with extremely high precision, excellent long-term stability, and very low 1/f noise. It is ideally suited for high-speed photodiode applications. The OPA380 features an offset voltage of 25 ?V, offset drift of 0.1?V/°C, and bias current of 50pA. The OPA380 far exceeds the offset, drift, and noise performance that conventional JFET op amps provide. As a result of the high precision and low-noise characteristics of the OPA380, a dynamic range of 4 to 5 decades can be achieved. For example, this capability allows the measurement of signal currents on the order of 1nA, and up to 100 ?A in a single I/V conversion stage. In contrast to logarithmic amplifiers, the OPA380 provides very wide bandwidth throughout the full dynamic range. By using an external pull-down resistor to –5V, the output voltage range can be extended to include 0V.
