The ADTL082A and ADTL084A are improved versions of The A grade amplifiers are available in lead-free packaging. The TL08x A, I, and Q grades. The ADTL082J and ADTL084J are standard grade amplifiers are available in both leaded and lead- industry alternatives to the TL08x standard and C grades. free packaging. The ADTL08x family offers lower noise, offset voltage, offset The ADTL082A and ADTL084A are specified over the extended drift over temperature, and bias current over the TL08x. In industrial (40C to +125C) temperature range. The ADTL082J addition, the ADLT08x family has better common-mode and ADTL084J are specified over the commercial (0C to 70C) rejection and slew rates. temperature range. These op amps are ideal for various applications, including process control, industrial and instrumentation equipment, Rev.
