WIDEBAND, LOW NOISE, LOW DISTORTION FULLY DIFFERENTIAL AMPLIFIER  
FEATURES  
DESCRIPTION  
Fully Differential Architecture  
The THS4511 is a wideband, fully-differential oper-  
ational 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 –72  
dBc HD2 and –87 dBc HD3 at 70 MHz with 2 Vpp,  
G = 0 dB, and 200-load. Slew rate is very high at  
4900 Vµs and with settling time of 3.3 ns to 0.1% (2  
V step) it is ideal for pulsed applications. It is  
designed for minimum gain of 0 dB.  
Common-Mode Input Range Includes  
the Negative Rail  
Unity Gain Stable  
Bandwidth: 1.6 GHz (Gain = 0 dB)  
Slew Rate: 4900 V/µs  
0.1% Settling Time: 3.3 ns  
HD2: –72 dBc at 70 MHz  
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.  
HD3: –87 dBc at 70 MHz  
OIP2: 76 dBm at 70 MHz  
OIP3: 42 dBm at 70 MHz  
Input Voltage Noise: 2 nV/Hz (f > 10 MHz)  
Noise Figure: 21.8 dB (50 System, G = 6 dB)  
Output Common-Mode Control  
5-V Power Supply Current: 39.2 mA  
Power-Down Capability: 0.65 mA  
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.  
Test and Measurement  
The THS4511 is offered in a Quad 16-pin leadless  
QFN package (RGT), and is characterized for oper-  
ation over the full industrial temperature range from  
–40°C to 85°C.
