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 ±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 observe common-mode input-vol...
