The ADTL082A and ADTL08A are improved versions of TL08x A-, I- and Q- grades. The ADTL082 and ADTL08 offer improvements over the TL08x standard and C-grades. The ADTL08x family offers lower noise, offset voltage, offset drift over temperature, and bias current over the TL08x. In addition, the ADLT08x family has better common-mode rejection and slew rate. These op amps are ideal for various applications including Rev. PrA Information furnished by Analog Devices is believed to be accurate and reliable.

The A-grade amplifiers are available in lead-free packaging. The standard grades are available in both leaded and lead-free packaging. For high precision grades of these devices, see the ADA000-2 (dual) and ADA000- (quad). The ADTL082A and ADTL08A are specified over the extended industrial (- to 25 C) temperature range. The ADTL082 and ADTL08 are specified over the commercial ( to C) temperature range. One Technology Way, P.O. Box 906, Norwood, MA , U.S.A. Tel: Fax: Analog Devices, Inc. All rights reserved.
