Signal Range to В±19 V description
The TLE208x 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. The TLE208x also have 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 TLE208x 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 these amplifiers 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.
Because BiFET operational amplifiers are designed for use with dual power supplies, care must be taken to …
