The ADTL082A and ADTL084A are improved versions of TL08x A, I, and Q grades. The ADTL082J and ADTL084J are industry alternatives to 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 rates. These op amps are ideal for various applications, including process control, industrial and instrumentation equipment, active filtering, data conversion, buffering, and power control and monitoring. The A grade amplifiers are available in lead-free packaging. The standard grade amplifiers are available in both leaded and leadfree packaging. The ADTL082A and ADTL084A are specified over the extended industrial (−40°C to +125°C) temperature range. The ADTL082J and ADTL084J are specified over the commercial (0°C to 70°C) temperature range.

If this is not possible, the input current must be limited to 10 mA. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ESD CAUTION Rev.
