The offset voltage (0.2Sm V maximum for the L grades) and Eoffset voltage drift (Sf LV/o Cmaximum for the L grades) are TEexceptionally low for high speed operational amplifiers. PRODUCT HIGHLIGHTS I. Laser trimming techniques reduce offset voltage drift to Sf LVr C max and reduce offset voltage to only 2S0f LV max on the L grade versions. 2. Analog Devices FET processing provides l OOp A max (20p A typical) bias currents specified after 5 minutes of warm-up. 3. Internal frequency pensation, low offset voltage, and full device protection eliminate the need for external ponents In addition to superior low drift performance, the AD381 and and adjustments. This reduces circuit size and plexity AD382 offer the lowest guaranteed input bias currents of any and increases reliability. wideband FET amplifier with l OOp Amax for the J grades of each and SOp Amax for the AD382 K, L and S grades. Since Analog Devices, unlike most other manufacturers, specifies input bias current with the amplifiers warmed-up, our FET 4. The fast settling output (700ns to 0.1%) makes the AD381 and AD382 ideal for D/A and AID converter amplifier applications. amplifiers are specified under actual operating conditions. The AD381 and AD382 are especially designed for use in applications, such as precision high speed data acquisition systems and signal conditioning circuits, that require excellent input parameters and a fast, high power...
