TLE2062AIDR

The TLE206x series low-power JFET-input op amps double the bandwidth of the earlier TL06x and TL03x BiFET families without significantly increasing power consumption. Texas Instruments' Excalibur process also provides a lower noise floor than the TL06x and TL03x. On-chip zener-trimmed offset voltage delivers precision-grade performance for DC-coupled applications. TLE206x devices are pin-compatible with other Texas Instruments BiFET op amps; they can be used to double the bandwidth of TL06x and TL03x circuits, or to reduce the power consumption of TL05x, TL07x, and TL08x circuits by nearly 90%. BiFET op amps offer the inherently high input impedance of JFET input transistors without sacrificing the output drive capability associated with bipolar amplifiers. This makes them better suited for interfacing with high-impedance sensors or low-level AC signals. They also provide superior AC response characteristics compared to bipolar or CMOS devices with equivalent power consumption. The TLE206x family features a high-output drive circuit capable of driving 100Ω loads from supplies as low as ±5V. This makes them particularly well suited for driving transformer loads in modems and other applications requiring good AC characteristics, low power consumption, and high output drive. Because BiFET op amps are designed for dual-supply operation, care must be taken to observe common-mode input voltage limits and output swing when operating from a single supply. The input signal must be DC-biased, and the load should be terminated to a virtual ground node at the midpoint of the supply. When operating a BiFET amplifier from a single supply, Texas Instruments' TLE2426 integrated virtual ground generator is extremely useful.
