FEATURES  
DESCRIPTION  
The THS4531 is a low-power, fully-differential op amp  
with input common-mode range below the negative  
rail and rail-to-rail output. The device is designed for  
low-power data acquisition systems and high density  
applications where power consumption and  
dissipation is critical.

Fully-Differential Architecture  
Bandwidth: 36 MHz  
The device features accurate output common-mode  
control that allows for dc coupling when driving  
analog-to-digital converters (ADCs). This control,  
coupled with the input common-mode range below  
the negative rail and rail-to-rail output, allows for easy  
interface from single-ended ground-referenced signal  
sources to successive-approximation registers  
(SARs), and delta-sigma (ΔΣ) ADCs using only  
single-supply 2.5-V to 5-V power. The THS4531 is  
also a valuable tool for general-purpose, low-power  
differential signal conditioning applications.  
Slew Rate: 200 V/µs  
THD: –120 dBc at 1 kHz (1 VRMS, RL= 2 kΩ)  
Input Voltage Noise: 10 nV/√Hz (f = 1 kHz)  
High DC Accuracy:

VOS Drift: ±4 µV/˚C (–40°C to +125°C)  
AOL: 114 dB
