OPERATIONAL AMPLIFIERS  
FEATURES  
DESCRIPTION  
•
Low Noise  
The THS3120 and THS3121 are low-noise,  
high-voltage, high output current drive, current-  
feedback amplifiers designed to operate over a wide  
supply range of ±5 V to ±15 V for today's high  
performance applications.  
– 1 pA/√Hz Noninverting Current Noise  
– 10 pA/√Hz Inverting Current Noise  
– 2.5 nV/√Hz Voltage Noise  
•
•
High Output Current Drive: 475 mA  
The THS3120 offers a power saving mode by provid-  
ing a power-down pin for reducing the 7-mA quiesc-  
ent current of the device, when the device is not  
active.  
High Slew Rate: 1700 V/µs (RL = 50 Ω,  
VO = 8 VPP  
)
•
•
•
Wide Bandwidth: 120 MHz (G = 2, RL = 50 Ω)  
Wide Supply Range: ±5 V to ±15 V  
These  
amplifiers  
provide  
well-regulated  
ac  
performance characteristics. Most notably, the 0.1-dB  
flat bandwidth is exceedingly high, reaching beyond  
90 MHz. The unity gain bandwidth of 130 MHz allows  
for good distortion characteristics at 10 MHz. Coupled  
with high 1700-V/µs slew rate, the THS3120 and  
THS3121 amplifiers allow for high output voltage  
swings at high frequencies.  
Power-Down Feature: (THS3120 Only)  
APPLICATIONS

Video Distribution  
Power FET Driver  
Pin Driver  
Capacitive Load Driver  
The THS3120 and THS3121 are offered in a 8-pin  
SOIC (D), and the 8-pin MSOP (DGN) packages with  
PowerPAD™.
