The offset voltage (0.2SmV maximum for the L grades) and Eoffset voltage drift (SfLV/oCmaximum for the L grades) are TEexceptionally low for high speed operational amplifiers. PRODUCT HIGHLIGHTS I. Laser trimming techniques reduce offset voltage drift to SfLVrC max and reduce offset voltage to only 2S0fLV max on the L grade versions. 2. Analog Devices FET processing provides lOOpA max (20pA typical) bias currents specified after 5 minutes of warm-up. 3. Internal frequency compensation, low offset voltage, and full device protection eliminate the need for external components In addition to superior low drift performance, the AD381 and and adjustments. This reduces circuit size and complexity AD382 offer the lowest guaranteed input bias currents of any and increases reliability. wideband FET amplifier with lOOpAmax for the J grades of each and SOpAmax 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 output. 5. The AD382's high output current (SOmA minimum at :t 10 volts) makes it suitable for driving terminated (200n) twisted pair cables over the commercial temperature ranges. 6. The high slew rate (30V/fLS) and high gain bandwidth product (SMHz) make the AD381 and AD382 an ideal choice for The AD381 and AD382 are offered in three commercial versions, sample and holds and for high speed integrator circuits. J, K and L specified from 0 to + 70°C, and one extended tem- perature version, the S specified from - 55°C to + 125°c. All grades are packaged in hermetically sealed metal cans. ) Information furnished by Analog Devices is believed to be accurate and reliable.
