Signal Range to В±19 V description/ordering information
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.
The TLE207x family of BiFET amplifiers are Texas Instruments highest performance BiFETs, with tighter input
offset voltage and ensured maximum noise specifications. Designers requiring less stringent specifications but …
