GENERAL DESCRIPTION
process control, industrial and instrumentation equipment,
active filtering, data conversion, buffering, and power control
and monitoring.
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 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 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.
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.
These op amps are ideal for various applications including
