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 Texas Instruments 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 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 Instruments TLV2432 and TLV2442 CMOS operational amplifiers
are excellent choices to consider.
