GENERAL DESCRIPTION
The Analog Devices ADIOIA, AD201A, AD301A and
AD301AL are high performance monolithic operational ampli-
fiers. All the circuits feature full short circuit protection, ex-
ternal offset voltage nulling, wide operating voltage range, and
the total absence or "latch-up". Because frequency compensa-
tion is performed externally with a single capacitor (30pF
maximum), the AD lOlA, AD20lA, AD30lA and AD30lAL
provide greater flexibility than internally compensated ampli-
fiers since the degree of compensation can be fitted to the
specific system application.
The ADlOlA and AD20lA have identical specifications in the
TO-99 package; the former guaranteed over the -55°C to
+12SoC temperatUre range, and the latter over ~2SoC to +8SoC.
The AD20lA is also available in the mini-DIP package for high
performance operation over the 0 to +70°C temperature range.
The AD30lA is specified for operation over the 0 to +70°C
temperature range in both the TO-99 and mini-DIP packages.
The AD30lAL is the highest accuracy version of this series.
Improved processing and additional electrical testing allow the
user to achieve precision performance at low cost. The device
provides substantially increased accuracy by reducing errors
due to offset voltage (O.SmV max), offset voltage drift
(S.OpV
/C max), bias current (30nA max), offset current
(SnA max), voltage gain (80,000 min), PSRR (90dB min),
and CMRR (90dB min). The AD30lAL is also specified
from 0 to +70° C and is available in the TO-99 can or 8-pin
mini-DIP.

'The maximum desirable junction temperature of the ADIOIA is +lSO°C; that of the AD201A, AD301A and AD301AL is
+lOO°C. For operating at elevated temperatures, devices must be derated based upon a thermal resistance of +lSO°CfW,
junction to ambient, or
+4SoCfW,
junction to case. The thermal resistance of the Dual In-Line package is +160°CfW, junction
to ambient.
2For supply voltages less than ~lSV, the absolute maximum input voltage is equal to the supply voltage.
. For the AD301A and AD301AL continuous short circuit is allowed for case temperatures to +70° C and ambient temperatures
to +SSOC.
.Unless otherwise specified, these specifications apply for supply voltages and ambient temperatures of ~SV to ~20V and -55°C
to +12SoC for the ADIOIA, ~SV to ~20V and -25°C to +8SoC for the AD201AH (0 to +70°C for the AD201AN), and ~SV to
HSV and 0 to +70°C for the AD301A and AD301AL.
