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/
Hz, 17-nV/
Hz 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
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
seeking the improved ac characteristics of the TLE207x should consider the TLE208x operational amplifier
family.
Because BiFET operational amplifiers are designed for use with dual power supplies, care must be taken to
observe common-mode input voltage limits and output swing when operating from a single supply. DC biasing
of the input signal is required and loads should be terminated to a virtual ground node at mid-supply. Texas
Instruments TLE2426 integrated virtual ground generator is useful when operating BiFET amplifiers from single
supplies.
The TLE207x are fully specified at
15 V and
5 V. For operation in low-voltage and/or single-supply systems,
Texas Instruments LinCMOS families of operational amplifiers (TLC- and TLV-prefix) are recommended. When
moving from BiFET to CMOS amplifiers, particular attention should be paid to slew rate and bandwidth
requirements and output loading.
