DESCRIPTION/ORDERING INFORMATION
The THS4511 is a fully differential operational
amplifier designed for single-supply 5 V
data-acquisition systems. It has very low noise at
2 nV/Hz, and extremely low harmonic distortion of
–76 dBc HD2 and –88 dBc HD3 at 70 MHz with
2 Vpp, G = 14 dB, and 100 load. Slew rate is very
high at 5100 V/μs and with settling time of 5.5 ns to
1% (2 V step) it is ideal for pulsed applications. It is
designed for minimum gain of 6 dB.
To allow for dc coupling to ADCs, its unique output
common-mode control circuit maintains the output
common-mode voltage within 5 mV offset (typical)
from the set voltage, when set within ±0.5 V of
mid-supply. The common-mode set point is set to
mid-supply by internal circuitry, which may be
over-driven from an external source.
The THS4511 is a high-performance amplifier that
has been optimized for use in 5 V single-supply data
acquisition systems. The output has been optimized
for best performance with its common-mode voltages
set to mid-supply, and the input has been optimized
for performance over a wide range of common-mode
input voltages. High performance at a low
power-supply voltage enables single-supply 5 V
data-acquisition systems while minimizing component
count.
The THS4511 is offered in a 16-pin ceramic flatpack
package (W), and is characterized for operation over
the full military temperature range from –55°C to
125°C.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those specified is not implied.
(2) The absolute maximum temperature under any condition is limited by the constraints of the silicon process.
