description  
The first members of TI’s new BiMOS general-purpose operational amplifier family are the TLC08x. The BiMOS  
family concept is simple: provide an upgrade path for BiFET users who are moving away from dual-supply to  
single-supply systems and demand higher ac and dc performance. With performance rated from 4.5 V to 16  
V across commercial (0°C to 70°C) and an extended industrial temperature range (−40°C to 125°C), BiMOS  
suits a wide range of audio, automotive, industrial, and instrumentation applications. Familiar features like offset  
nulling pins, and new features like MSOP PowerPADpackages and shutdown modes, enable higher levels  
of performance in a variety of applications.  
Developed in TI’s patented LBC3 BiCMOS process, the new BiMOS amplifiers combine a very high input  
impedance, low-noise CMOS front end with a high-drive bipolar output stage, thus providing the optimum  
performance features of both. AC performance improvements over the TL08x BiFET predecessors include a  
bandwidth of 10 MHz (an increase of 300%) and voltage noise of 8.5 nV/Hz (an improvement of 60%). DC  
improvements include an ensured V  
that includes ground, a factor of 4 reduction in input offset voltage down  
ICR  
to 1.5 mV (maximum) in the standard grade, and a power supply rejection improvement of greater than 40 dB  
to 130 dB. Added to this list of impressive features is the ability to drive 50-mA loads comfortably from an  
ultrasmall-footprint MSOP PowerPAD package, which positions the TLC08x as the ideal high-performance  
general-purpose operational amplifier family.
