The TL05x series of FET-Input operational amplifiers offers improved dc and ac characteristics over the TL07x and TL08x families of FET operational amplifiers. Texas Instruments improved FET process and optimized designs also yield improved bandwidth and slew rate without increased power consumption. The TL05x devices are pin-compatible with the TL07x and TL08x and can be used to upgrade existing circuits or for excellent performance in new designs.
FET operational amplifiers offer the inherently higher input impedance of the FET-Input transistors, without sacrificing the output drive associated with bipolar amplifiers. This makes them better designed for interfacing with high-impedance sensors or very low-level ac signals.
The TL05x family are designed to offer higher precision and better ac response than the TL08x, with the low noise floor of the TL07x. Designers requiring significantly faster ac response can consider the Excalibur TLE208x and TLE207x families of FET operational amplifiers.
Because FET 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 terminated to a virtual-ground node at mid-supply. Texas Instruments TLE2426 integrated virtual ground generator is useful when operating FET amplifiers from single supplies.
The TL05x are fully specified at ±15V and ±5V. For operation in low-voltage and/or single-supply systems, Texas Instruments LinCMOS families of operational amplifiers (TLC-prefix) are recommended. When moving from FET to CMOS amplifiers, particular attention to be paid to the slew rate and bandwidth requirements, and also the output loading.
