PRODUCT DESCRIPTION
The ADS09j, ADS09K and ADS09S are monolithic
operational amplifiers specifically designed for applications

requiring fast settling times to high accuracy. Other compar-
able dynamic parameters include a small signal bandwidth of
2OMHz, slew rate of lOOV/JlS min and a full power response
of 150kHz min. The devices are internally compensated for
all closed loop gains greater than 3, and are compensated with
a single capacitor for lower gains.

The input characteristics of the AD.509 are consistent with

0.01 % accuracy over limited temperature ranges; offset current
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.

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
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.

PRODUCT HIGHLIGHTS

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
deterioration in settling time. Larger capacitive loads
can be driven by tailoring the compensation to minimize
settling time.

3. Common Mode Rejection, Gain and Noise are compatible
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.
