GENERAL DESCRIPTION

The ADTL082 and ADTL084 are JFET-input amplifiers

providing industry-leading performance over TL08x devices.

The ADTL082A and ADTL084A are improved versions of

TL08x A-, I- and Q- grades. The ADTL082 and ADTL084 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

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 grades are available in both leaded and lead-free

packaging. For high precision grades of these devices, see the

ADA4000-2 (dual) and ADA4000-4 (quad).

The ADTL082A and ADTL084A are specified over the extended

industrial (-40° to 125°C) temperature range. The ADTL082 and

ADTL084 are specified over the commercial (0° to 70°C)

temperature range.
