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.
