5962-9460204QHA description

The TLE207x series of JFET-input operational amplifiers more than double the bandwidth and triple the slewrate of the TL07x and TL08x families of BiFET operational amplifiers. Texas Instruments Excalibur processyields a typical noise floor of 11.6 nV/√Hz, 17-nV/√Hz ensured maximum, offering immediate improvement innoise-sensitive circuits designed using the TL07x. The TLE207x also has wider supply voltage rails, increasingthe dynamic signal range for BiFET circuits to ±19 V. On-chip zener trimming of offset voltage yields precisiongrades for greater accuracy in dc-coupled applications. The TLE207x are pin-compatible with lowerperformance 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, withoutsacrificing the output drive associated with bipolar amplifiers. This makes them better suited for interfacing withhigh-impedance sensors or very low-level ac signals. They also feature inherently better ac response thanbipolar or CMOS devices having comparable power consumption.The TLE207x family of BiFET amplifiers are Texas Instruments highest performance BiFETs, with tighter inputoffset voltage and ensured maximum noise specifications. Designers requiring less stringent specifications butseeking the improved ac characteristics of the TLE207x should consider the TLE208x operational amplifierfamily.Because BiFET operational amplifiers are designed for use with dual power supplies, care must be taken toobserve common-mode input voltage limits and output swing when operating from a single supply. DC biasingof the input signal is required and loads should be terminated to a virtual ground node at mid-supply. TexasInstruments TLE2426 integrated virtual ground generator is useful when operating BiFET amplifiers from singlesupplies.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. Whenmoving from BiFET to CMOS amplifiers, particular attention should be paid to slew rate and bandwidthrequirements and output loading.Copyright © 1997 − 2004, Texas Instruments IncorporatedPRODUCTION DATA information is current as of publication date.Products conform to specifications per the terms of Texas Instrumentsstandard warranty.
