GENERAL DESCRIPTION
The ADTL082 and ADTL084 are JFET input amplifiers that
provide industry-leading performance over TL08x devices.
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,

and monitoring.
The A grade amplifiers are available in lead-free packaging. The
standard grade amplifiers are available in both leaded and lead-
free 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.
