DESCRIPTION
The TLE206x series of low-power JFET-input operational amplifiers doubles the bandwidth of the earlier generation TL06x
and TL03x BiFET families without significantly increasing power consumption. Texas Instruments Excalibur process also
delivers a lower noise floor than the TL06x and TL03x. On-chip zener trimming of offset voltage yields precision grades for
dc-coupled applications. The TL206x devices are pin-compatible with other TI BiFETs; they can be used to double the
bandwidth of TL06x and TL03x circuits, or to reduce power consumption of TL05x, TL07x, and TL08x circuits by nearly 90%.
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 TLE206x family features a high-output-drive circuit capable of driving 100-Ω
loads at supplies as low as ±5 V. This makes them uniquely suited for driving transformer loads in modems and other
applications requiring good ac characteristics, low power, and high output drive.
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 TLE206x 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-prefixes) are recommended. When moving from BiFET
to CMOS amplifiers, particular attention should be paid to slew rate and bandwidth requirements, and output loading. The
Texas Instrument TLV2432 and TLV2442 CMOS operational amplifiers are excellent choices to consider.
