THS4508  
www.ti.com  
SLAS459A–SEPTEMBER 2005–REVISED FEBRUARY 2006  
WIDEBAND, LOW NOISE, LOW DISTORTION FULLY DIFFERENTIAL AMPLIFIER  
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.

Minimum Gain of 2 V/V (6 dB)  
Bandwidth: 2 GHz  
The THS4508 is a high-performance amplifier that  
has been optimized for use in high performance, 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 best performance with  
its common-mode voltage set to 0.7 V. High  
performance at a low power-supply voltage makes for  
high-performance single-supply 5-V data-acquisition  
systems with a minimum parts count. The combined  
performance of the THS4508 in a gain of 10-dB  
driving the ADS5500 ADC, sampling at 125 MSPS, is  
82-dBc SFDR, and 68.3-dBc SNR with a –1-dBFS  
signal at 70 MHz.  
Slew Rate: 6400 V/µs  
0.1% Settling Time: 2 ns  
HD2: –72 dBc at 100 MHz  
HD3: –79 dBc at 100 MHz  
OIP2: 78 dBm at 70 MHz  
OIP3: 42 dBm at 70 MHz  
Input Voltage Noise: 2.3 nV/√Hz (f > 10 MHz)  
Noise Figure: 19.2 dB (G = 10 dB)  
Output Common-Mode Control  
5-V Power Supply Current: 39.2 mA  
Power-Down Capability: 0.65 mA  
The THS4508 is offered in a Quad 16-pin leadless  
QFN package (RGT), and is characterized for  
operation over the full industrial temperature range  
from –40°C to 85°C.
