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,

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 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.
