The TL03x series of FET-input operational amplifiers offer improved DC and AC characteristics over the TL06x family of low-power operational amplifiers. The Texas Instruments improved FET process and optimized designs also yield improved bandwidths and slew rates without increased power consumption.
FET operational amplifiers offer the inherently higher input impedance of the FET-input transistors. This higher input impedance makes the TL03x amplifiers better suited for interfacing with high-impedance sensors or very low-level AC signals.
The TL03x family has been optimized for micropower operation, while improving on the performance of the TL06x series. Designers requiring significantly faster AC response must consider the TLE206x family of low-power FET operational amplifiers.
The FET operational amplifiers are designed for use with dual power supplies, therefore take care 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 must be terminated to a virtual-ground node at mid supply. The TI TLE2426 integrated virtual-ground generator is useful when operating amplifiers from single supplies.
The TL03x devices are fully specified at ±15V and ±5V. For operation in low-voltage and/or single-supply systems, the TI LinCMOS families of operational amplifiers (TLC prefix) are recommended.
The C-suffix devices are characterized for operation from 0°C to 70°C. The I-suffix devices are characterized for operation from −40°C to 85°C.
