FEATURES
DESCRIPTIO
The LT®1220 is a high speed operational amplifier with
superior DC performance. The LT1220 features reduced
input offset voltage, lower input bias currents and higher
DCgainthandeviceswithcomparablebandwidthandslew
rate. The circuit is a single gain stage that includes
proprietary DC gain enhancement circuitry to obtain pre-
cisionwithhighspeed. Thehighgainandfastsettlingtime
make the circuit an ideal choice for data acquisition
systems. The circuit is also capable of driving large
capacitive loads which makes it useful in buffer or cable
driver applications.

The LT1220 is a member of a family of fast, high perfor-
mance amplifiers that employ Linear Technology
Corporation’s advanced complementary bipolar process-
ing. For applications with gains of 4 or greater the LT1221
can be used, and for gains of 10 or greater the LT1222 can
be used for increased bandwidth.

Note 4: Input offset voltage is pulse tested and is exclusive of warm-up drift.
Note 5: Slew rate is measured between ±10V on an output swing of ±12V.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: A heat sink may be required when the output is shorted indefinitely.
Note 6: FPBW = SR/2πV .
P
Note 3: Commercial parts are designed to operate over –40°C to 85°C, but
are not tested nor guaranteed beyond 0°C to 70°C. Industrial grade parts
specified and tested over –40°C to 85°C are available on special request.
Consult factory.
Note 7: Differential Gain and Phase are tested in A = 2 with five amps in
series. Attenuators of 1/2 are used as loads (75Ω, 75Ω and 499Ω, 499Ω).

APPLICATIONS INFORMATION
The LT1220 may be inserted directly into HA2505/15/25,
HA2541/2/4,AD817,AD847,EL2020,EL2044andLM6361
applications, providedthatthenullingcircuitryisremoved.
The suggested nulling circuit for the LT1220 is shown in
the following figure.
Layout and Passive Components
The LT1220 amplifier is easy to apply and tolerant of less
than ideal layouts. For maximum performance (for ex-
ample, fast settling time) use a ground plane, short lead
lengthsandRF-qualitybypasscapacitors(0.01µFto0.1µF).
For high driver current applications use low ESR bypass
capacitors (1µF to 10µF tantalum). Sockets should be
avoided when maximum frequency performance is re-
quired, although low profile sockets can provide reason-
able performance up to 50MHz. For more details see
Design Note 50. Feedback resistors greater than 5k are not
recommended because a pole is formed with the input
capacitance which can cause peaking or oscillations.

APPLICATIONS INFORMATION
Input Considerations
(i.e., 75Ω) should be placed in series with the output. The
other end of the cable should be terminated with the same
value resistor to ground.
Bias current cancellation circuitry is employed on the
inputs of the LT1220 so the input bias current and input
offsetcurrenthaveidenticalspecifications.Forthisreason,
matching the impedance on the inputs to reduce bias
current errors is not necessary.
DAC Current-to-Voltage Amplifier
The high gain, low offset voltage, low input bias current,
and fast settling of the LT1220 make it particularly useful
as an I/V converter for current output DACs. A typical
application is shown with a 565A type, 12-bit, 2mA full-
scale output current DAC. The 5k resistor around the
LT1220 is internal to the DAC and gives a 10V full-scale
outputvoltage.A5pFcapacitorinparallelwiththefeedback
resistor compensates for the DAC output capacitance and
improves settling. The output of the LT1220 settles to
1/2LSB (1.2mV) in less than 300ns. The accuracy of this
circuit is equal to:
Capacitive Loading
The LT1220 is stable with capacitive loads. This is accom-
plishedbysensingtheloadinducedoutputpoleandadding
compensation at the amplifier gain node. As the capacitive
load increases, both the bandwidth and phase margin
decrease. There will be peaking in the frequency domain as
shown in the curve of Frequency Response vs Capacitive
Load. The small-signal transient response will have more
overshoot as shown in the photo of the small-signal
responsewith1000pFload.Thelarge-signalresponsewith
a 10,000pF load shows the output slew rate being limited
to 4V/µs by the short-circuit current. The LT1220 can drive
coaxialcabledirectly, butforbestpulsefidelityaresistorof
value equal to the characteristic impedance of the cable
VERROR = VOS + (IOS • 5kΩ) + (VOUT/AVOL)
Atroomtemperaturetheworst-caseerroris3mV(1.2LSB).
Typicallytheerroris1.2mV(1/2LSB).Overthecommercial
temperature range the worse-case error is 6mV (2.5LSB).
