Key Features
- High input impedance due to JFET-input transistors, making it suitable for interfacing with high-impedance sensors or low-level AC signals.
- Double the bandwidth of the earlier TL06x and TL03x BiFET families without significantly increasing power consumption.
- On-chip zener trimming of offset voltage for improved DC performance.
- High output drive, specified into 100-Ω loads, even at low supply voltages (±5 V).
- Lower noise floor compared to earlier generations of low-power BiFETs.
- Pin-compatible with other TI BiFETs, allowing for easy upgrades or substitutions in existing circuits.
Applications
- Interfacing with high-impedance sensors or very low-level AC signals.
- Driving transformer loads in modems and other applications requiring good AC characteristics, low power, and high output drive.
- DC-coupled applications where precision grades are necessary.
- Low-voltage and/or single-supply systems, although LinCMOS families (TLC- and TLV-prefixes) are recommended for such applications.
