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.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
