FEATURES
High Slew Rate 30V/p,s
Fast Settling to 0.1%: 700ns
High Output Current: 50mA for AD382
(10mA for AD381)

OBPRODUCT DESCRIPTION
SThe AD3811AD382 are hybrid operational amplifiers combining
the very low input bias current advantages of a FET input stage
Owith high slew rate and line driving capability of a high power
Loutput stage.
The offset voltage (0.2SmV maximum for the L grades) and
Eoffset voltage drift (SfLV/oCmaximum for the L grades) are
TEexceptionally low for high speed operational amplifiers.
PRODUCT HIGHLIGHTS
I. Laser trimming techniques reduce offset voltage drift to
SfLVrC max and reduce offset voltage to only 2S0fLV max on
the L grade versions.
2. Analog Devices FET processing provides lOOpA max (20pA
typical) bias currents specified after 5 minutes of warm-up.
3. Internal frequency compensation, low offset voltage, and full
device protection eliminate the need for external components
In addition to superior low drift performance, the AD381 and
and adjustments. This reduces circuit size and complexity
AD382 offer the lowest guaranteed input bias currents of any
and increases reliability.
wideband FET amplifier with lOOpAmax for the J grades of
each and SOpAmax for the AD382 K, L and S grades. Since
Analog Devices, unlike most other manufacturers, specifies
input bias current with the amplifiers warmed-up, our FET
4. The fast settling output (700ns to 0.1%) makes the AD381
and AD382 ideal for D/A and AID converter amplifier
applications.
amplifiers are specified under actual operating conditions.
The AD381 and AD382 are especially designed for use in appli-
cations, such as precision high speed data acquisition systems
and signal conditioning circuits, that require excellent input
parameters and a fast, high power output.
5. The AD382's high output current (SOmA minimum at :t 10
volts) makes it suitable for driving terminated (200n) twisted
pair cables over the commercial temperature ranges.
6. The high slew rate (30V/fLS) and high gain bandwidth product
(SMHz) make the AD381 and AD382 an ideal choice for
The AD381 and AD382 are offered in three commercial versions,
sample and holds and for high speed integrator circuits.
J, K and L specified from 0 to + 70°C, and one extended tem-
perature version, the S specified from - 55°C to + 125°c. All
grades are packaged in hermetically sealed metal cans.
