Designs description
The TL03x series of JFET-input operational amplifiers offer improved dc and ac characteristics over the TL06x
family of low-power BiFET operational amplifiers. On-chip zener trimming of offset voltage yields precision
grades as low as 1.5 mV (TL031A) for greater accuracy in dc-coupled applications. The Texas Instruments
improved BiFET process and optimized designs also yield improved bandwidths and slew rates without
increased power consumption. The TL03x devices are pin-compatible with the TL06x and can be used to
upgrade existing circuits or for optimal performance in new designs.
BiFET operational amplifiers offer the inherently higher input impedance of the JFET-input transistors without
sacrificing the output drive associated with bipolar amplifiers. This higher input impedance makes the TL3x
amplifiers better suited for interfacing with high-impedance sensors or very low-level ac signals. These devices …
