Signal Range to В±19 V description
The TLE207x series of JFET-input operational amplifiers more than double the bandwidth and triple the slew
rate of the TL07x and TL08x families of BiFET operational amplifiers. Texas Instruments Excalibur process
yields a typical noise floor of 11.6 nV/в€љHz, 17-nV/в€љHz ensured maximum, offering immediate improvement in
noise-sensitive circuits designed using the TL07x. The TLE207x also has wider supply voltage rails, increasing
the dynamic signal range for BiFET circuits to В±19 V. On-chip zener trimming of offset voltage yields precision
grades for greater accuracy in dc-coupled applications. The TLE207x are pin-compatible with lower
performance BiFET operational amplifiers for ease in improving performance in existing 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 makes them better suited for interfacing with
high-impedance sensors or very low-level ac signals. They also feature inherently better ac response than
bipolar or CMOS devices having comparable power consumption. …
