description The TLE206x series of low-power JFET-input operational amplifiers doubles the bandwidth of the earlier generation TL06x and TL03x Bi FET 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-patible with other Texas Instruments Bi FETs; 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%. Bi FET 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 parable 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 Bi FET operational amplifiers are designed for use with dual power supplies, care must be taken to observe mon-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 Bi FET 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 Lin CMOS families of operational amplifiers (TLC- and TLV-prefixes) are remended. When moving from Bi FET to CMOS amplifiers, particular...
