OB ~ TPRODUCT DESCRIPTION
The ADS09j, ADS09K and ADS09S are monolithic
Soperational amplifiers specifically designed for applications
requiring fast settling times to high accuracy. Other compar-
Oable dynamic parameters include a small signal bandwidth of
L2OMHz, slew rate of lOOV/JlS min and a full power response
of 150kHz min. The devices are internally compensated for
Eall closed loop gains greater than 3, and are compensated with
a single capacitor for lower gains.
TEThe input characteristics of the AD.509 are consistent with
1. The ADS09 is internally compensated for all closed loop
gains above 3. and compensated with a single capacitor for
lower gains thus eliminating the c:laborate stabilizing tech-
niques required by other high speed IC op amps.
2. The ADSO9 will drive capaciti~ loads of SOOpF without
0.01 % accuracy over limited temperature ranges; offset current
deterioration in settling time. Larger capacitive loads
is 2SnA max, offset voltage is 8mV max, nullable to' zero, and
offset voltage drift is limited to 30p.V/'C max. PSRR and
CMRR are typically 90dB.
can be driven by tailoring the compensation to minimize
3. Common Mode Rejection, Gain and Noise are compatible
The ADS09 is designed for use with high speed D/A or AID
conveners where the minimum conversion time is limited by
the amplifier setding time. If 0.01 % accuracy of conversion
is required. a conversion cannot be made in a shoner period
with a 0.01 % accuracy device.
4. The ADSO9K and ADSO9S are 100% tested for minimum
slew rate and guaranteed to settle to 0.01% of its final
value in less than 2.Slls.
than the time required for the amplifier to settle to within
0.01 % of its final value,
All devices are supplied in the TO-99 package. The ADS09j
and ADS09K are specified for 0 to +70oC temperatUte range;
the ADS09S for operation from -SSoC to +12SoC.
