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 an automotive temperature range (–40°C to 125°C), BiMOS suits a wide range of audio, automotive, industrial, and instrumentation applications. Familiar features, such as offset nulling pins, and new features, such as MSOP PowerPAD. packages 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 VICR that includes ground, a factor of 4 reduction in input offset voltage down to 1.5 mV (maximum), 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 ultra-small-footprint MSOP PowerPAD package, which positions the TLC08x as the ideal high-performance general-purpose operational amplifier family.
